How to Use the Investment Property Calculator
Real estate investors need to run the numbers before committing to a deal. This calculator is built for that purpose — whether you are evaluating a fix-and-flip, analyzing a rental property's cash flow, or modeling a DSCR loan scenario. It covers the loan types that matter most to investors: Fix & Flip, DSCR (Debt Service Coverage Ratio), Bridge, and Construction loans.
To use the calculator, select your loan type, then enter the relevant deal metrics — purchase price, rehab budget, expected after-repair value (ARV), or monthly rental income depending on the scenario. The calculator returns your estimated loan amount, monthly debt service, cash flow projections, and DSCR ratio. These numbers help you quickly evaluate whether a deal pencils out before you spend time on due diligence.
A note on availability: Investor loan programs are available in Michigan and most other states across the country. If you are investing outside of Michigan and are unsure whether your state is covered, reach out and we will confirm before you go further in the process.
How to Interpret Your Investment Calculator Results
The most important number for rental property investors is the DSCR — Debt Service Coverage Ratio. This is your monthly rental income divided by your monthly loan payment. A DSCR of 1.0 means your rent exactly covers your mortgage. Most DSCR lenders require a ratio of 1.1 to 1.25, meaning your rent needs to exceed your payment by 10 to 25 percent. If your DSCR comes out below 1.0, the deal may not qualify for a DSCR loan without a larger down payment or a lower purchase price.
For fix-and-flip scenarios, the key metric is your loan-to-ARV ratio — the loan amount as a percentage of the after-repair value. Most fix-and-flip lenders cap this at 65 to 75 percent of ARV. If your numbers show a loan-to-ARV above that threshold, you may need to negotiate a lower purchase price, reduce your rehab budget, or bring more cash to the deal.
Frequently Asked Questions
What is a DSCR loan and how does it work?
A DSCR loan qualifies you based on the rental income of the property rather than your personal income. There are no W-2s or tax returns required. The lender calculates the property's debt service coverage ratio — if the rent covers the mortgage payment at the required ratio, you qualify. This makes DSCR loans ideal for self-employed investors or those with complex income structures. Learn more on our Rental Property Loans page.
What credit score do I need for an investment property loan?
Most investor loan programs require a minimum credit score of 620 to 680, though requirements vary by loan type. Fix-and-flip lenders may have more flexible credit requirements than DSCR lenders. Your loan officer will review your full profile and identify which programs you qualify for based on your situation.
Are investor loans available outside of Michigan?
Yes — our investor loan programs are available in Michigan and most other states. If you are investing in a different state and want to confirm availability, contact us and we will let you know before you move forward.
How much down payment is required for an investment property?
Down payment requirements vary by loan type. DSCR loans typically require 20 to 25 percent down. Fix-and-flip loans are often structured around the ARV and may require less cash down if the deal has strong equity. Bridge loans and construction loans have their own structures. Your loan officer will walk you through the options that fit your deal.
