@Danae Pitcher, my STR requires a different policy through a different insurer, my LTR policies and umbrella won’t cover STR.

The park's rules requires at least 1 member to be 55+ on the application, so it appears that the co-applicant could be under that age.

I would require a signed lease from them as well as a security deposit. 

With residential properties and hard money lenders, they will usually have an option for financing the property's renovations as well.There are a couple of caveats: first, most lenders will require a property down payment.

Although we were not able to get 3.5% as a down payment, we were able to get a 10% loan requirement as well as financing for the property remodel rolled into the same loan.

@Nathan Frost- correct -the " interest " only payment  is often made  monthly along with the  monthly taxes and insurance so the only thing missing from this  sort of payment  would be the  principal  amount that  would be  required  on a normal amortizing loan  (  which isnt a huge  amount  ) 

Second home requires a minimum of 10% down and show (2) years of employment, income and good to fair credit to qualify.

The EV charger is listed as an amenity on our Airbnb listing.Cost $1800 for Tesla charger installation.One interesting insight is that we couldn't get 100% charge ability from the charger because our house's electrical was sized for 225 amps (the electrician sized it for the house's electrical requirements at the time, the charger was an add-on afterwards). 

In regards to bedrooms, the county requires a permit and they will determine your occupancy based on the BR size (1 person for the first 70 s.f. then you can add additional person for each 50 s.f. after), parking, and parcel size.

Some of our clients have even installed two separate electric meters on the property, which would require two separate addresses.
