Throw pillows only when visibly dirty.

Most DSCR loans want to see only 90 days of seasoning (including the ~30 days it takes to refinance).Some programs might make an exception if you've done some rehab to it, but given your scenario I think you could just get a tenant in there, stabilize it, and get started on the refi in about a month or so.

It might do better than expected, but you won't know till you try it one season.

I am looking into purchasing a seasonal trailer site and an adjacent industrial lot with Quonset.

I like the logo pillows! 

Great to have seasoned professionals like you here—looking forward to learning from your perspective and networking together.

The no-seasoning option with DSCR loans definitely changes the game for BRRRR investors who want to recycle capital quickly.From my experience, the bigger hurdle tends to be conservative appraisals rather than seasoning.

Since this will be a vacation rental that your family wants to enjoy, I would focus on STR for high season & the seasons you want to stay and MTR the rest of the year. 

And can use STR rental income with less seasoning if the borrower has experience.
