It doesn't sound like a showstopper to me.Did you ask the plumber if there is anything people can flush that will help keep the lines clear?

Anything with a class 5 rating flush would be fine.

They were getting it flushed several times a year!

We buy the cabinet hardware in bulk on Amazon and do flush mount hinges, new handles and knobs.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

I think I let my ego get the best of me and instead of doing a cash for keys I went straight to court.  

You can go straight down on one block and straight up around the corner.

Based on the numbers seems like it was a straight forward conventional loan...any challenges?

If it is someone you know you can give them a straight return as if its a loan - can provide a lower interest rate to provide upside - it really depends on the lender and what are they concerned with and what is their risk profile. 

Never heard of Investor's Edge, but this sounds like a straight up scam.
