@Roee Hazut at the end of the day, anyone can tell you not buy blind 1k miles away without ever setting foot on a plane.

At that point I can either put in an offer or book a plane ticket.  

Same for paper delivery, UPS, FEDEX?

I would send the notice by certified mail/FEDEX/UPS or a process server to ensure receipt.

If it did every tenant would control their landlord/business investor.For you to even consider not issuing a planed increase due to your tenants situation shows you lack the business head to maximise your returns and are tending toward operating your business as a social worker.

Is it OK to start a lease and Fedex Mail it back and forth?

I would say if you are planing to work with this officer see if you can get some references, you don't want to work with someone who is not knowledgeable.

It's out of the flood plane and there are beautiful homes on both sides.Is there a way to convert the wetlands (basically just a wooded foresty area) into build-able lots?

Only get into a deal like this if you're able to 1) go to the area and meet everyone involved in person, 2) research the area on your own so you really know what houses cost and what rents are (hint: prices and rents where you live in Miami are completly irrelevant), and 3) are willing to get on a plane and go deal with an issue if need be.

I am planing to paint my primary but can't decide on going with same color for living room, kitchen and dining or multiple colors.
