(Obviously in Vegas we have zero siding or roof expenses so your mileage may vary.)Good luck. 

.”• I pay all the costs – things like Real Estate Commission - Title Insurance - Escrow Fees - Transfer Tax -Termite Clearance - Roof Certification – the list goes on and on..• And I buy them in an “as is” condition.

An extra $200/mo. to me wouldn't be worth it to have so many families/people under one roof.

(they do charge a flat $2 for ACH, but tenants will pay that).

You can have two properties with similarly sized roofs in two completely different neighborhoods at different cost points. 10% "might" be a starting point, but it depends on a lot.

The brokerage offers an appealing Flat Fee 100% commission program.

Well basically I have had connections to help with the roof on to help gut the house as well as try to GC some of the little bit of stuff I needed done but far as that just the finance guyWhat was the outcome?

BUT, I had to put on a new roof which I didn't think I needed.

Lots of things come immediately to mind:  Septic problems, a new roof, HVAC failure, lower-than-projected rents. 

and most of the time is  bad management, bought the wrong price, Interest and Insurance to the roof and, I cant get out the Bridge loan to do a DSCR loan etc ...Simple hands on, work do research and minimize risk.
