This would also allow me to keep my primary at a low rate loan. 

I'd love to have a small line of credit on the property before the end of the year to cover any other repairs or upgrades that will need to go into the property.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

If you have a 9% rate and you need to get down to the low  7s and cash out, then maybe it could make sense.

For your first commercial deal, your best home is probably going to be with a local community bank or credit union. 

Either way its good to buy end of year as most builders and sellers are offering seller credits or builder credits to use towards closing costs or to buy a rate down to help get a lower payment.Even if you wanted to buy a strater home like a 2-4 unit as a primary again you only need to put 5% down. 

More competition equals less income per cabin.It's possible you can grab a cabin at a low price from someone who bought at the peak in 2022,  Just do your homework and be sure you can make your ROI before you enter this market.

Those "good contractors" usually have the lines of credit or means to pay for supplies up front if they know they will be paid on time and are not desperate for a deposit to go get the supplies.

Perhaps slightly higher from an alternative lender but definitely not from a credit union and expect much higher fees.

A few showings, one low ball...but this time of year in that area, things just slow down.
