Maybe they keep a record of addresses of drug busts.

This has already delayed my target closing date about a week, which was locked in with the interest rate.My main concerns are as follows:1.  

I would use postcards because letters from unknown addresses hardly ever get opened. 

The house does need exterior paint.My questions and concerns are for those who have had experience with investment properties from this time Period.

If that is not a concern then having a large negative cash flow is a huge financial and emotional stress.

Once I looked up the address, I find out the location is a high volume selling liquor store.

Some counties will only list the pin number, billable owner, and/or parcel number of a property and you are left to research individually each record to ascertain the property address or land use.

He's very concerned the state could take it away and because this land was his parent's land, now his, and he wants it to become ours and later our son's, he's very concerned modern laws will stop this.
