The attorney's I use have stated that the online sites do not technically supply all the information required in the bill and stated that if the landlord wants they can probably not accept any of the current online sites like Zillow.

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

What you are referring to is a  DSCR loan which the lending companies do provide, they do require decent down payment and it must have good cash flow.

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

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.

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  ) 

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.
