I have a total of $10k in closing costs - I believe as an investment property(in the name of my LLC) I can claim all these amounts and deductible over life of loan i.e 30 yrs so 10,000/30 = $333/year - Is that correct? 

Hopefully I’m posting this in the correct location.  

I've turned to treasuries as buffers in the short term (ie - TLT), yet the market will always rebound (who knows if this is full on Bear or another manufactured correction), I wouldn't abandon the market completely.

It's possible the tenant is better at this sort of work than both of us but you never really know...If I were in your shoes, I'd have a licensed contractor do plumbing and electrical but that will cost you more.I guess it comes down to whether or not you want to pay more or take a chance the tenant is doing it correctly, in which case you can simply be happy that the tenant is happy and also that he's saving you $, at least in the short run.

Is your after repair value correct? 

Dan is correct.

Yes correct, 10 year tax abatements. 

If we have the zoning changed or updated to the correct zoning, will we fall in that commercial classification? 

I checked with the correct authority, they have no record of a tank or a decommissioning.If the seller told you that's how "it was decommissioned"... and the garage smelled like fuel oil, how would you respond?

What do you do to ensure that the tenant is responsible for security deposit disputes since that is the largest reason for owner lawsuitsHow familiar are you with the newly changed laws that can affect you the owner if they are not used correctly?.
