Would you help is wedding coordinating/planning or just rent the space out?

-I do not plan on becoming a real estate mogul with 100 doors to my name More like 15-20 to supplement my wealth building.

I believe the current road structures / plans favor accessibility for those towns verses Clayton to the south.

For CLE, a quick search took me to the Planning Commission's website and it looks like you can request a review by the Board of Zoning Appeals and, if approved, get a building permit to change your zoning/use.

When the tenant renews the lease I plan to bump up rent $50 so I'll only be paying $20.

Are you comfortable buying anything in Tulum given the amount of building going on and planned and therefore the competition you'll face when renting? 

If you're planning on doing most of the general trades yourself you don't need a GC.

We actually plan to take it back up to further repair the subfloor, and then re-install :-p. 

Maybe this is normal but it seemed ridiculous to expect someone to keep their job(s) and pay rentSince it seemed I was left with no option except to plan on getting prepared to pay March and get the house in good shape so my deposit would be returned and bite the bullet.

If you plan to continue working in houses like this, yes, it's worth developing this skill.Look online for how to use oxalic acid and peroxide cream developer to lighten floors, the actual technique you'll use.
