I understand your concerns.

I'm looking into purchasing a rental property in the Belmont area of Dayton, OH and wanted to get any insight for this market as it seems concerning that the average rent is higher compared to the actual costs of houses in the area.

Depends on really what you are looking for:-Speed - some HMLS can go "no appraisal" so can close very quickly and beat cash offers if you are in a competitive market to buy-Interest Rates - can range anywhere from around 8% to 13% (same with "points") but not usually as huge of a concern for flippers since the terms are so short-Leverage - depending on your risk appetite / capital - this is also a top concern for some (almost always over and above rates/fees) can see anywhere from around 80% LTC to even mid 90s LTC (including 100% of rehab budget)
