What is the best method to basically cold call or write to a person who owns the vacant lot next to my rental house.

Dustin,Thanks for the details on you method.  

Corrosive to HVAC plumbing and electrical very hard on the Lungs especially for a compromise immunity system, to identify the Chinese drywall go up in the attic and look at the backside of the drywall in the ceiling you will see Chinese printing in red.

To be honest, that 4 bedroom could easily be turned into 2 large 2 bedroom 1 bath units (there are already 2 baths and the plumbing is in place for another kitchen.Here's the thing.

Electrical, plumbing, roof, windows were updated in 2006.Asking: $98,000.  

So I have to conduct a lot of business via email or voicemail tag which isn't the most efficient method of conducting business and causes things to take forever.

Actually its a shell ( it does have wiring and plumbing) with nothing but the walls .

You've got a major plumbing and wiring job if you don't want to include utilities in the rent, and even if you do you need to run either 220 or gas for the stoves.

I do drywall, floors, paint, tile, plumbing, and more!!!

from a legal standpoint, you can even wire and plumb your own house, as long as it passes code and inspection.
