I am no fan of banks.Some ideas when negotiating for seller financing:Offer to give them more for a principal mortgage (no interest)Build in a discount for early pay offIt should be a subordinated mortgage (meaning you can place that mortgage in a lower position) if you decide to refinance and the bank wants first position.Put in a "substation of Collateral" clause - meaning you can "walk" the mortgage to another property if you sell the property and won't have to pay it off - it will just be on another property with suitable collateral.As for 11 payments a year instead of 12 (Xmas bonus)Good luck with your deal ---- Charles

I have read that may make me eligible for bonus depreciation, but how does that work if I’m only using one unit as a short term rental/primary?

He wrote the bonus chapter in the 30-Day Stay book.

Can someone help me understand the future of bonus depreciation?

Nothing wrong with using credit card sign up bonuses and cash back for a rehab if you have the actual cash to pay it off.

Also accelerated or bonus depreciation from other RE can assist in offsetting capital gains.

Let the new resident decide for themselves.Yup...we always market these as:"3 bedrooms PLUS LARGE BONUS ROOM that could be used as FOURTH bedroom, Office, Playroom, Media Room, Library or Recreation Room!"

Take the 30-year and if there is an opportunity to refi down the line, than that is a bonus.

You'd have to be a fool to think there's no opportunity in STR/MTR right now.I've noticed that the new host referral bonus has increased from $500ish to over $700 in the last couple months. 

Bonus Question: Will a market correction fix my problem or make it worse?
