I really want to systemize my approach so it's thorough, cohesive, and not a waste of valuable time.Areas on my list currently: Akron OH, Albany NY, Birmingham AL, Boise ID (I'm from there so there's familiarity), Cincinnati OH, Cleveland OH, Columbia SC, Delaware County PA, Memphis TN, Oklahoma City OK, Philadelphia PA, Pittsburg PA, Richmond VA, St Louis MO, Tampa FL, Wilmington DESo yeah, a lot there and I know I'm missing many.

The vast majority of cases are settled out of court. 

In more complex appraisals like this, there is the added variable that every appraiser has a different level of skills, knowledge, experience, and a vast array of different perspectives on the best way to value you a property.

I own a house with a garage apartments, house is rented for $900, it currently has 2 efficiency apartments renting @ $500 month, the first level is a 600sq ft. 2 car garage w/ a cellar & 8’ ceiling height, currently vacant, it was renting for $100 to a previous tenant...The entire building needs windows, siding & a roofHere is my question; do you recommend spending an additional 25-30k to build out the garage into a 1 bedroom apt?

I break homes up in to 3 categories and they all have different considerations.Pre-WWII homes - homes with plaster/lathe walls, probably old coal chutes, block or brick basements (sometimes cellar conversions,) originally knob and tub wiring and galvanized plumbing, original hardwood floors, old wood windows, etc.

They did note that the vast majority of the evictions filed were worked out without having to remove the resident.

The bottom line is that the vast majority of arbitrage renters tend to be unprofessional cash grabbers.

Any sales, or long term lease transaction that does not include paying off a non assumable mortgage note will result in a violation of the “due on sale” clause of the mortgage or deed of trust, with one remedy being the acceleration of the note by the lender ( demanding immediate note payoff), within state law guidelines.History has shown that in the vast  majority of cases lenders have NOT accelerated the notes when these violations took place.  

(90%+, numbers change depending on the survey).I’ll believe the vast majority of scientists, and ignore the small percent who disagree for whatever reason.

You wouldn't have sold what you did for what you did and expect a vastly different shopping experience).
