While rates may not decrease, the significant double-digit increases should level off.

I have dabbled in real estate, but never heard of brrrr before now, and transparently never did much research outside of knowing that property ownership was a way to reduce my taxable income. 

I would strongly consider building equity to make a stronger down payment and further decrease your monthly cost. 

2) wouldn't the interest be taxable to seller?

One group wants housing prices to increase, the other wants them to decrease. 

The longer term loans would have lowered your monthly payments and decreased the costs.As for rent, each year you need to look at rents in the area to decide how much you will be increasing the rent by. 

My questions are;Do I have to take expenses as a deduction in a year in which they occurred even if I do not get income until the following year  I have other rental property, but my taxable income on them after expenses is only gonna be about $5000 So is there anyway to roll over expenses to the next year since I cannot deduct the remaining 15,000 and expenses against my W-2 income?

But there's something else that many people don't realize: these loans  "constant recast" during the interest-only period.For example, if I make an extra $400 payment one month, my interest-only payment will decrease the following month.

However, can I say that I gave a rebate to myself on that transaction for the full RE Agent Commission amount and decrease the cost basis of my house accordingly?

And if you convert it to a rental you’ll be facing a $200k taxable gain.
