Thanks for posting @Randy E.This article has been circulating quite a bit in my neighborhood (Germantown, Philadelphia).

Crexi and Loopnet are not particularly good sources for deals - properties only wind up there after they've been circulated through brokers' contact network and the good ones have been picked out.I'd also recommend that you dig a bit deeper into the underwriting and invest on more than just cap rate. 

This allows warm air to circulate around the pipes and prevent freezing.

J Scott - Like I said while licensed there was an office memo that circulated that stated that they could no longer block individuals from membership to the MLS.

Maybe physical dollar bills an coins will fall out of circulation, but the money in your checking and savings account is still technically cash. 

If it is a breath ability issue  because the house is too tight for air circulation with mildew then the wiping method can sometimes work.

What they do: 1. find moisture / leak / fix2. air circulation  fans/ open windows day and night3. remove drywall, any fabric, porous material and replace  any new material you bring in will have some mold Everything has mold, it's in the air.

Similar to window and portable, it is blowing air in just one location.Of all the AC types, central air is most desirable because it circulates air better.

Water circulating correctly.Feb 1 - Tenant informs me that it wasn't warm last night.

This will lead to hot and cold areas in the house unless you add additional circulation e.g ceiling fans.
