Hey @Rio Nance you’re casting a pretty wide net with your question, since it's not specific to an area or city, but I’ll share based on what I'm seeing.

Across the board, the worse the neighborhood, the better the cash flow, the better the neighborhood, the trade off for tenants base, better schools, low crime, etc etc.

You take that best guide as a base and put your own spin on it but make sure you don't copy proprietary content or do plagiarism.

I believe it's because the property is being sold "as-is," and they are unwilling to make repairs or negotiate based on findings.

Since I'm based in Tampa, I don't look outside and compare markets. 

$25k is only 4.16% of your new purchase price, heck of a deal.Thank you for your service and let me know if you want to talk any more details and run actual numbers based on your situation.

I base my rents on the condition of the unit and the competition. 

Then make your decision based on information.  

This method provides an indication of value based on the property's rents.

It looks like you are doing an affordable build based on the cost but hard to say since you didnt provide info on the build itself such as square footage and finishes.
