Am I getting any extra from it that I can't from here?  

HOWEVER, want to avoid/minimize setting up a new company and filing additional LLC and other related documents (want to avoid extra work additional docs would create). 

I see why many of us on BP want to keep admin work to a minimum and reduce the necessity of extra entities and extra bank accounts, but these are things that the big players do. 

If you spend the extra money to stay in the deal how many years will it take to recoup your investment taking into account appreciation & income?  

I am planning on renting the house out for roughly $1950 to have some extra income to use when showing income for my next loan.

In Florida it is common for drywallers to charge extra for a flat finish because of the extra labor.In my area buyers expect/want textured walls and ceilings, except for the old variants mentioned above, which they hate and can actually negatively affect the selling price of the home.

They also mentioned their would by extra cost on their power bill “which they are responsible for” from having to run the well pump for an hour or 2 to shock and flush the system!

Their official policy is that they will not pay more than market rent.Also @Clint Jusino mentions taking extra rent on the side. 

Expensive GC who I have confidence in but I'd rather not spend the extra $ unless it's highly advisable.2.

I would certainly rather have the tenant pay $3,500 and personally pay an extra $100-$500 for a whole new unit.
