Getting approved for a loan to buy investment property feels exciting—and sometimes a little overwhelming. I remember the first time I started looking at rental properties and quickly realized financing them was a world apart from buying my own home. Over the years, with experience and plenty of research, I learned how the process works, what banks look for, and where the differences really matter. If you’re searching for a clear, honest guide on financing real estate investments in the U.S., you’re in the right place.
Understanding investment property loans vs. primary residences and second homes
The difference between these property types matters, both for lenders and for you as a buyer. Here’s how I see it:
- Primary residence: This is your main home, the place you return to most nights. Loans for these homes usually have the lowest rates and flexible requirements because lenders assume you’ll make paying for your home a priority.
- Second home: Think vacation home or a place you visit on weekends. It can’t be rented out full-time, and lenders want you to use it yourself at least some of the year.
- Investment property: This is real estate purchased to generate income—through rent, resale, or both. It might be a single-family house, a duplex, or even a small apartment complex. Mortgage requirements are more strict for these because the risk is higher for banks if you have financial challenges.
It’s important to be clear about your intent from day one. In my experience, lenders check occupancy—so always be honest in your loan application. If you need an introduction into the world of real estate investments and strategies, I recommend reading about real estate investment strategies in the U.S.
Types of investment property financing available
Not all loans are created equal, especially for property investors. I want to break down the options you might see:
- Conventional mortgages: These are similar to the loans you’d use for a house, but standards (like down payment and credit score) are higher. They’re available for one-to-four-unit properties. You can read more details about this type of mortgage in the conventional programs guide from Heart Mortgage.
- Portfolio loans: Offered by some lenders, these loans stay “in-house” instead of being sold to third parties. Guidelines may be more flexible, but terms can vary.
- Lines of credit: If you own property already, a home equity line of credit (HELOC) or a business line of credit can fund new investments.
- DSCR loans: Debt Service Coverage Ratio (DSCR) loans look at the property’s potential rental income rather than your personal income. DSCR loans can help investors who don’t meet strict traditional income requirements.
- Multifamily and vacation home loans: Financing larger buildings or specialty use properties has additional requirements—higher down payment, more documentation, and sometimes commercial licenses.
Sometimes I get questions about loans for foreign nationals or those without permanent residency status in the U.S. There are options for those as well, and if this is you, the Heart Mortgage guide for buying property in the U.S. without a Green Card is very helpful.
Qualifying for a loan on investment property
I’ve seen many would-be investors get caught off guard by how much more lenders ask for in this process compared to buying a home to live in. Here's what you need to prepare:
- Down payment: Lenders often require at least 20-25% down for investment properties. Some might accept less, but be ready for higher rates or mortgage insurance if so. For multifamily properties or loans over four units, a 25% or even 30% down payment is common.
- Credit score: A minimum score of 620 is needed by most lenders, but better rates usually start at 700. For the best rates and terms, aim for 740 or higher.
- Rental income: Lenders often count projected rental income, especially with DSCR or multifamily loans. You’ll need to show market rent analysis or current lease agreements.
- Cash reserves: You may need to show enough savings to cover six months (or more) of mortgage payments, taxes, and insurance. This reassures lenders you can absorb vacancies or emergencies.
- Other debts: Your overall debt-to-income ratio still matters. Lenders want to see you have room in your budget to cover all monthly obligations.
Every loan type and lender may set different minimums, but these requirements are a good starting point. Heart Mortgage’s approach is to review your situation individually and offer advice about where you stand—or where you need to be before moving forward.
What documents and financial prep you’ll need
Paperwork is part of the journey. It’s always better to gather documents before starting the formal application for investment financing. From my experience, here’s what you should pull together:
- Recent pay stubs and W-2s (if employed) or tax returns (if self-employed/own a business).
- Recent bank statements (usually last two or three months).
- Retirement/investment account statements if you’ll use these for the down payment or reserves.
- Signed purchase agreement for the property (once under contract).
- Information about other real estate you own—including leases, mortgage statements, and insurance.
- Proof of funds for down payment and closing costs.
- Documentation of projected or current rental income—either lease agreements or a rent schedule from an appraiser or real estate professional.
As you can see, lenders want a clear picture of your finances. This is to be sure you can handle the costs involved, even if the property is vacant for a time.
Walking through the application and approval process
When I walk clients through their first investment property loan, I always stress that patience helps. Here is a typical sequence:
- Start with a pre-qualification or pre-approval. This gives you an idea of what you can afford, and what documentation needs improvement.
- Find your desired investment property and submit a contract. Then, your lender can move your file into underwriting.
- Provide requested documentation. Be quick—delays can affect your closing timeline.
- The lender handles an appraisal, looking at both the property’s value and expected rental income (when applicable).
- The underwriter reviews all information, checks credit and calculates ratios. If satisfied, they issue a “clear to close.”
- You sign final paperwork, transfer funds for the down payment and closing costs, then receive the keys.
Loan approval is a team effort—be transparent and proactive.
One thing I have learned is that it’s always helpful to consult with someone who specializes in investment property lending. The loan process has more moving parts than financing a primary residence.
Common loan options and comparing the rates
When evaluating loan choices, it’s tempting to look only at the interest rate. But there is a lot more to weigh:
- Fixed-rate loans: Safe and steady; payments stay consistent.
- Adjustable-rate loans: Lower initial payment but may increase in the future. Good for short-term holds, but riskier if you plan to keep the property long-term.
- Interest-only loans: Helpful for cash flow early on, but you’ll owe the entire principal eventually.
- DSCR and portfolio loans: Can come with higher rates but are tailored for investors.
Investment loans often come with higher rates than owner-occupied mortgages, stricter qualifying criteria, and bigger down payments. That’s because lenders consider them riskier. It’s smart to compare not just the rate, but also lender fees, prepayment penalties, and overall monthly payments.

Watching for risk factors and the value of expert guidance
Real estate investing can bring financial rewards, but it comes with higher risks than buying a personal residence. Vacancies, unexpected repairs, and market shifts all play a role. I always tell new investors: An experienced mortgage advisor can help you spot risks and compare loan options that fit your goals, not just your application.
Some risks that make investment lending different:
- Interest rates may be significantly higher.
- Lenders may limit how many financed properties you can have.
- Cash reserve requirements can limit immediate cash flow.
- Insurance is more expensive for rental or multifamily property.

Frequently asked questions
What is an investment property loan?
An investment property loan is financing used to buy real estate that is intended to generate income, such as rental properties or properties to resell. This type of loan often has stricter requirements than loans for homes you plan to live in, because lenders see more risk in properties used solely for profit. The repayment, rates, and screening process can all differ from loans for primary or secondary residences.
How to qualify for an investment property loan?
To qualify, you will need a higher credit score (usually 620 or above), a larger down payment (commonly 20% or more), documented proof of income and assets, and cash reserves. Lenders will also review your total debts and likely consider the rental income the property can produce. Your financial stability and the performance of the property both play a role in approval.
How much down payment is needed?
For most investment property loans in the U.S., a down payment of at least 20% is required. For multifamily units or larger buildings, you may need 25% or even higher. Other factors, like the property type and your overall financial profile, could push that required percentage even higher in particular cases.
What credit score do I need?
Lenders usually want to see a credit score of 620 or higher for investment properties, but you’ll get better loan rates and terms if your score is at least 700-740. Keeping existing debts low and maintaining good payment history are the best ways I’ve found to strengthen your credit fast.
Where to find the best loan rates?
The best rates are often found by comparing several lending options and by consulting with experienced mortgage specialists.
