Investor Calculator FAQ

What’s the difference between NOI and cash flow?

NOI (Net Operating Income) is what the property earns after operating expenses but before the mortgage. Cash flow is what’s actually left in your pocket after the mortgage payment. A property can have strong NOI and still cash flow poorly if the financing terms aren’t great.


What does DSCR mean and why does it matter?

DSCR stands for Debt Service Coverage Ratio. It measures whether the property’s income can cover the mortgage. A DSCR of 1.0 means you’re breaking even on debt coverage. Most lenders want to see 1.15 or higher, and some DSCR loan programs use this number instead of your personal income to qualify you.


What’s a good cap rate for a rental property in Western New York?

 It depends on the area and property type, but in Western NY markets like Buffalo, Niagara Falls, and Lockport, investors typically look for cap rates in the 7–10% range. Higher cap rates usually mean more risk or more work. Lower cap rates in stronger neighborhoods can still make sense if you’re focused on appreciation and stability.


What’s a realistic vacancy rate to use?

A 5–8% vacancy rate is a reasonable starting point for most Western NY rentals. If the property is in a high-demand area or you have a strong tenant history, you might go lower. For rougher areas or properties that need work, budget higher. Don’t use 0% vacancy, even great landlords have turnover.


Should I include repairs and renovations in this calculator?

This calculator is built for analyzing ongoing rental performance once the property is stabilized. If you’re buying a property that needs significant work before renting, use the BRRRR Calculator instead. It factors in rehab costs, the refinance, and post-renovation cash flow together.


What’s the difference between maintenance and CapEx?

Maintenance covers routine, recurring costs like fixing a leaky faucet or replacing an appliance. CapEx (capital expenditures) is for bigger, less frequent expenses like a new roof, furnace, or windows. Both matter. A lot of new investors only budget for maintenance and get caught off guard by a $12,000 roof. Budget for both every month, even when nothing breaks.


How much cash do I actually need to buy a rental property in Western NY?

The calculator estimates your all-in cash needed, which includes your down payment, closing costs, and any rehab. On a typical investment property in Western NY, expect to put down 20–25% for conventional financing. Add 2–4% for closing costs and whatever rehab the property needs. Having reserves on top of that is smart, most lenders and experienced investors recommend 3–6 months of expenses in the bank after closing.

Estimates only. Actual expenses and loan terms vary by property condition, town, insurance quotes, and lender guidelines.
