This can be attractive to a seller because they can be protected via promissory note, personal guarantee, etc. 

Located in Port Orange FL just south of Daytona close to many attractions.

My plan was to keep it for 15-20 years as its in a good area and it attracts high quality tenants and wait for the appreciation gain.

What kind of crowd does it attract?

From your description of your debt you have more than 2 times your annual income in consumer debt so you are unfortunately not attractive to lenders.Sorry to sound so negative but you asked. 

The broader point is that $30k, $700 rentals:- Will generally attract C class tenants and require higher capex accruals- Will not have much room for professional management- Will not produce the paper returns most investors think they will due the squeeze on IRR by lack of appreciation- CAPEX is a very REAL expense and is an accrued liability that simply cannot be ignored.

And there is nothing you can do to those shares to make them more attractive than the other 100 million shares out there, and sell them for a higher price.

A financing contingency will protect you but it will also make your offer less attractive to the seller.

If you guarantee them a 10 or 12% return, that is almost always more attractive for a 6 month timeline, even if they are loaning you 5 or 10k.  

Tourist there seem to be mostly American, Canadian and British, though I did run into some Chinese and Japanese.8.
