He claims it was due to him closing the account because his truck was broken into and checks and other personal material was stolen.He claimed he was going to send a new check, but that hasn't happened, and he's stopped responding to me.What are my best options at this point to collect the earnest money that he owes me contractually?

Many smaller storage facilities have some outdoor storage for Trucks, RV's, and other items on wheels.  

Here's an alternative link, let me know if this one works:  http://www.realtor.com/realestateandhomes-detail/615-W-Saint-Catherine-St_Louisville_KY_40203_M30498-88981.I'm with you on not living in or investing in rough parts of town which is why I never even look at anything in the west end.  

Couple of quick ones off the bat..... zoning, availability of alternate landlords,  FCC, FAA, neighborhood groups, surrounding property uses, etc.  

A demo contractor I know is on non conforming heavy commercial , there are houses around him , he makes lots of noise , starts trucks and equip at 4 am to leave for jobs , the neighbors hate it , the family business has been there over 50 years .

I'm sure it is a best practice but I have an attic without insulation, a tenant baking in the home and the three alternatives I'm faced with are: 1. exorbitant quotes from insulation companies.2. being told simply "I don't do it in the summer because it's to hot" 3. 

Anyone know of a good alternative on Android?

What about the tax implications of all three alternatives?

It is taxable.An alternate suggestion would be to go ahead and do a full exchange.
