You should understand that the advice and information in this solicitation is general and that your own situation may vary.

Our local contract states that when you request repairs/credits after a home inspection the sellers first response can not be to void the contract. 

My effort driving there would have been useless.My advice, if you have some bandwith in your cash flow, you should just call a handyman or have your tenants do it (and give them a rent credit) .I had one of my tenant install to 6 fence boards (literally just buy the materials at home depot and hammer nails on the fence posts).

Through that company I have an unused line of credit of $100,000.

How he interest is calculated will vary by state so you need to specify where the tax lien is located.

The judgement itself will appear on the credit report.

One is 45,000 square feet, the other 2500.I am looking for input as to whether you run: -personal credit report-business credit report-request tax returns for personal and businessAll of the above?

Adding AC should cost about $2500/unit plus the cost of running the electrical which varies but is approximately $1500.
