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?

This time I wanted to add a property to show that the benefits of cost segs on residential rentals may improve as the income producing properties increases.Not much has changed except for gross rental of 40k, designed to represent net income, has been added (you could also pretend to divide 40 across multiple properties)However, the bonus depreciation not used on the "Property A" gets transferred over to "Property B" (in effect).Although this doesn't offset W-2 income, don't ignore the fact rental income is taxed at ordinary rates, so the benefit is still there.I think the takeaway may be consider holding off on the bonus until you have more properties if there are insufficient, other passive activities to absorb the amounts.

BONUS ANSWER: Free to go to the county BUT the best place to go is to a Title Company or Closing Attorney and get a list from them.
