Also, this type of property will take some time to sell I’d assume, so carrying that mortgage for up to 6 months is not optimal.We have other properties(commercial) as well as a business (car wash) that remain positive cash flowing/profitable.  

If you have 2 years of tax returns showing that income to wash out the mortgage, you should be fine.

Be careful with turning on tax loss harvesting while you have vanguard, it may be considered a wash especially if both brokerages have a similar asset, unless Vanguard is a target date fund you may have issues. 

It's a wash, they owe the lender, you owe the seller.

It's vacant, homeowner probably does not have the capacity or desire to fix/rent it. and would like to wash their hands of it for the amount of the loans.  

Stain the trim, pressure-wash but don't paint vinyl.  

When you're done, wash all the window sills and window wells with TSP (any hardware store will have it).

that's just the bathtub, add the washing machine, and the rain gutters.

The worst I have ever had a tenant do, was he stole the coper lines as he was leaving and flooded my basement in the middle of winter.

Natural light is the best thing for a room.FYI - We cleaned up our garage floor with a strong solvent/cleaner years ago (sorry don't remember what we used, but got it at Home Depot) and it worked fine.
