ESRI has locked me out, but here is a link to City-Data which is just as effective.

They are surrounded by danger for 10-12 hours a day. 

There's a couple of sections in there dedicated to cost effective ways of improving a home to improve the ARV and some different pointers on materials too.

That being said, I’m not concerned too much about PMI’s unless it effects my CashFlow on the properties.

@Andrew Hyder Mail is effective in finding leads.

Some "cons" of the 203k are:MI (mortgage insurance) for the life of the loanUpfront MIP (mortgage insurance premium) can reduce the effect of the 3.5% down paymentCan take 15-30 days extra to closeNot all industry partners (Lender, Realtor, 203k Consultant, and Contractor) are as knowledgeable/experience as neededSlightly higher interest rate compared to FHA 203(b), which is the normal FHA loanCannot repair/add luxury itemsSome areas can have lower max loan limits that what is needed to do a 203kExcept for qualified non profit groups, required to be owner occupied for min 1 year  There are many pros to the 203k, but above are just some of the "cons." 

Statistics like this are fine when you look at a population as a whole but it doesn't take into effect the amount of effort put in by an individual.

@Laurent Meyer personal option: little will effect multifamily market. 

I know, I owned a gym for 6 years and got out before business was effected because it was becoming a grind.

If as I mentioned, we used 12% instead of 10% for PM fee, this would in effect add $141/month in "tenant replacement costs", if the tenant churns in 18 months we've "escrowed" $2,538 in total for the replacement - roughly 3x the actual cost.
