I got it all cleaned up (special crime scene clean up is expensive thank God for insurance) and was terrified it would not rent and that the neighbors would run off any prospective tenants with the story.

Here's what it looks like:Purchase price = $300kRental income = 4 x 1bd/1ba @ $500 , 2 x 2bd/1ba @ $650 = $3300, seller thinks  1bd's can go up to $700 and market research supports that Taxes = $200/monthEstimated expenses = 1300/month (10% each for vacancy, CAPEX, and repairs and $200/month for insurance)NOI = $23k at lower rents, $33k at higher rentsCash flow = $500 at lower rents, $1300 at high rentsThe property is in a C neighborhood that is gentrifying.
