One of my bigger concerns is that it is on well and septic -- my concern is more that I've never dealt with that before -- but the owner said he installed a brand new septic system last year at considerable cost -- and, of course, I'd have both systems inspected as a condition of sale. 

Until just before lease signing I had not thought about this with water being in my name, but water will be in the tenant's name going forward, so do I need to be concerned about continuing to water the grass using tenant paid water?

Thats my real concern.

I have concerns that I will be tying my hands a bit if I eventually want to sell / develop the two lots together or if I want to hold for a bit and draw lines of credit against the lots.Thanks,Juan Monge

The address is what is key not the current owner.  

When I did so, she told me I was supposed to have scheduled the walk-through and when I told her I didn't have time that day to do so, she told me it wasn't required, I could just leave the keys (and parking passes and laundry card) and a forwarding address to send me the security deposit refund.

“Point of contact information” refers to any means by which to contact the brokerage firm or individual licensee including mailing address(es), physical street address(es), e-mail address(es), telephone number(s) or facsimile telephone number(s).

So there is that concern, I don’t know when homes in my area were required to be build with 3 wire common ground electrical, and then there’s the plumbing of course, I don’t know when iron was no longer allowed either.

Of course, if you’re buying in 2018 a lot of these issues could have been addressed already.

I would be concerned that they would not pay the rent on time.However, if they do not have a credit score then it likely means they are able to pay cash for their expenses and do not have any debts.
