Apply for your short-term rental permit NOW in case the county stops issuing them or changes the rules in a manner in which you wont be able to get one in the future. 

I personally don't see this real estate price action as sustainable in the short term.

@Debbi Oshier mobile homes in a park are considered vehicles and are taxed in a similar manner that vehicles are, primarily based on the age of the home.

In this manner you should be able to purchase a much larger property.6.

Do not buy a mobile home parks that has:1) No operating permit as evidenced by a Certificate of Zoning.2) No demand as verified by running test advertisements.3) Failing private utilities unless you have an approved plan to fix them and can afford to do so.4) Dirt roads unless you have a lender that will finance it, or the capital budgeted to pave them.5) One individual (other than the park owner) that owns a huge number of the homes (most lenders will not make a loan if one person owns more than 5% of the homes).6) Does not have a clean Phase I environmental assessment.7) Does not have a clean survey.8) Does not have a clean title.9) Is overpriced in such a manner that you will not make money with it based on reasonable performance.10) Does not have a healthy risk/reward relationship (buy low risk with high reward and avoid high risk with low reward).

It is time to screen tenants and so I feel the need to be there in person doing this for a couple weeks (I don’t know if it takes that long) but this doesn’t seem sustainable.

This response is bit aged but adding here if helpful to others for similar future situations: If you are a US citizen or resident you are subject to US tax on your worldwide income, even if from a property in the DR or anywhere else in the world.Assuming you directly own the property as an individual, generally you're only going to generate a capital gain if you sell or dispose in some other manner the property.

Any solid and good mannered adviced would be extremely appreciated.

Not very many NICE properties are sold in this manner.  

So you're paying for a phone receptionist in the event of a maintenance issue.My area of concern is if their business is sustainable at $50 per month.
