I’m estimating renovation costs at around $150,000.

However what happens when the tenant vacates and now the unit has to be turned over/takes a few months to find a new tenant and during that same period of time the sewer line goes and you get hit with that $15,000 cap ex expense in addition to the vacancy and turn over costs.

Usually the numbers don't work to build in these neighborhoods, unless government tax credits, etc.Do you see the problem with your two statements:"The turnover costs could/will be high"and"How much more damage could they do?"

Subsequent images on the site show the property’s progressive deterioration over the years.Another property, a three-story rowhouse at 915 Dauphin St. near the Fairhill neighborhood, underwent a similar decline: Seven months after its November 2016 acquisition by DDH, it too had windows and doors.

This could include computer delays, the inability to reach the site, creating a late filing, and subsequent penalties.

If you ever want to get into a tenant nightmare of costly potential litigation become a landlord, have the ac go out in Phoenix in July, and inform the tenant that you just don’t have the funds to replace it!.    

I'll save you the details but...Per door cost: $63,300All in Cost: 700kTotal Revenue: 137k(ish) annuallyNOI: 65-73% (in the expenses we included: insurance, taxes, $75/month per door repair expense, management fee 8%, grass cutting, & a misc fund for random crap business license, etc.)Now...

EDUCATE YOURSELF - yes, it will take time, but will lead to a selection that better meets your expectations & avoids potentially costly surprises!

Hard money typically refers to a company that has it's own underwriting guidelines, rates (9% - 15%), costs, draw process ect.

Whether the seller was open to a buyer commission or not, I wouldn't put an additional cost into any personal purchase.
