Most “service dogs” are not service dogs, just like most folks parking in designated handicap parking places are not legitimately handicapped.  

You should use a state-specific lease that is clear regarding the start and end dates, the monthly rent, the fees that will be charged (ex. pets) and those that may be charged (ex late fee), the amount of the security deposit, and a clear list of rules associated with the property (no smoking inside is a big one as are rules related to parking).

Quote from @Rob Ibarra: Good afternoon BP,I came across an off-market overlooked listing for a 100 pad RV Park in GA and inquired on it, and waiting on a response from the owner.

The market for tiny house parking right now is probably bigger than for people interested in renting a tiny house.

Since you're in DFW, I could for example say the best appreciation market over the last 10 years is Highland Park, if appreciation is your goal. 

Do they fit in available parking?

I'm looking at 1 bed apartments (near the theme parks). $300k budget.

Dont' forget you can 1031 into a DST to "park" your funds if timing/consolidation is an issue, for example.I THINK you still need a Will, especially if property is across multiple states.Is your father a NYS resident? 

My wife and I had 5 SFH and 1 multi-family, sold all, 1031 into a commercial RV park, now living for free since other people pay our living expenses.

For example Caz park and Babcock district are both part of South Buffalo, however they are very different investment micro markets.
