We listed strategically and were under contract in 2 weeks in the slowest part of the year (December) whereas all the other similar homes in the neighborhood have been sitting for months and still sitting on the market. 

It's important to know what market rents are for what you are analyzing, many properties are super under rented and you have to get them to market rates. 

It is still a seller's market in many geographic locations, so you can ask potential buyers for an extended closing period and/or with options to extend the closing period. 

You may also be able to "make your market" if you can hit a critical mass.

What is the property appreciation in that market? 

Depends on your market and competition.

Last year, I purchased a SFH under market at 7.65% interest rate and did some rehab to up the value.

Quote from @Kevin Hintz: I can totally relate to the tight market and how hard it is to find deals.

I suspect most who requested cash for keys had previously received cash for keys.What I do instead is explain:- the housing shortage in my market and that an eviction will forever make it difficult to find a quality rental in this market. - I will ding their credit such that all credit cards and other debt will cost them more.- I will keep their security deposit for funds owed.- I will do my best to garnish future wages until their debt to me is paid in full.This has worked 100% time so far.
