My realtor says they’re pretty good but I am not sure an ARM is smart when I’m not putting a lot down and plan to keep this property long term.

Make sure it explicitly explains the process for termination if you are unhappy with their services, especially if they violate the terms of your agreement.3.

“They kind of tend to use the term on the assumption that everybody already knew what it meant.”'

Think long term and enjoy all the mailbox money.

You can do DSCR loans or Hard money loans, where they only focus on how well the subject property performs in terms of the rental aspects or the ARV aka after repair value.

If your are cash flow positive, you can weather long term through emergencies and other problems that could arise while you wait. 

If you do this you'll have a huge pile of money that will allow you to pursue whatever strategy you want very quickly.If I had to do it all over again, I would buy a personal residence as soon as I could, probably house hack, then buy a new personal residence as soon as I had the money for another down payment then turning the old house into a long term rental.If you're just starting I'd also recommend listening to the Bigger Pockets and Real Estate Rookie Podcasts.

Prepayment penalties- usually 1-5 year terms.

New to the forum and new to STR (Lots of long term experience), thanks all for the community.
