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  ) 

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.

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). 

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

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

  - There are certain requirements for the lease that vary from state to state.

Conventional refinance would require 12 month seasoning as per Fannie Mae/Freddie Mac guidelines, so you'd likely go with a DSCR refinance.

Hey Kelsey, Unfortunately, it's not that simple, since you need to consider your AGI (adjusted gross income) to get the real savings here and that requires doing your taxes quite literally from start to finish.

Maybe  DSCR 2nd if both the 1st and 2nd mortgages meet the debt service requirements.
