But during the buyer’s due diligence, several unexpected issues surfaced, each cutting deeper into the profit I had worked years to earn.The first issue was with the water lines.

I guess a lot of Scott's buyers are under water the day they sign a loan, so he must be regularly evicting and reselling some of those houses.

great alternative to small time investors with limited capital.. doing 20 though would be quite a bit of work.. selling coaching has basically zero liability when you start to manage investor capital your liablity goes up a ton in the unlikely event of a water landing..

I originally found BP to help myself nagivate the waters of RE.

This helps keep me out of hot water with fairhousing. 

I underestimated utilities in my early years, so I ensure those are properly captured (electricity, gas, water and trash).

And I did buy 13 lot package in Henry county but it was all sewer and water.. smokin deal 3k a lot held them 2 years and sold for 35k a lot :)@Jay Hinrichs excellent advice - always appreciate your insight!

Then based on @Michael Baum's suggestion, I think I will have my cleaner and/or maintenance person do monthly/quarterly maintenance like using using enzyme based cleaners, grease fighting drain treatments and hot water flushing. 

Granted this was on plots of land I didn't pay for, and that are already connected to the city's water and sewer, so there's a lot of savings there, but I'm hoping if it turns out to be this good of a deal I can still scoop up land and keep going

This is a beautiful house - rehabbed/looking new and fresh - walking distance to the water etc, yet low gross yield  compared to Byrd (???)
