Would encouraging longer stays realistically help reduce this, especially for a medium-sized cabin?

If house hacking, allocate expenses between personal and rental use to claim deductions only for the rental portion.

Then I had another one where the buyer brought as is under the impression that legalizing would be easy and found out it was not ever allowed and a portion of the structure had to be demolished because it was built horribly and a hazard as built.  

You could tell them to cancel the listing and you will find someone else to list it after a month not 4 months (the market take is subjective too, all dependent on what your house has compared to others, where it is located, the size of it, and so many other factors).

Depending on property size you can expect rents between $1500-$1850. 

Yeah the price is around 12k-15k for 7 people size.

Bonus depreciation is just a special part of the US tax code.It allows you to take accelerated depreciation on portions of your property depending on when an asset is put into service.At the time of this writing, you can write off a huge portion (60% in 2024) of many qualified components that have a useful lifespan of 15 years or less.That means a certain percentage of things like landscaping, sidewalks, latches, appliances, fences, certain flooring, etc is depreciable in year 1.The bonus depreciation rate percentage changes yearly depending on the administration and the tax code.For years 2015 through 2017 first-year depreciation for all the items on a 15-year schedule or less was set to 50%.It was scheduled to go down to 40% in 2018 and 30% in 2019 and then 0% in 2020.But then Trump got elected, and he enacted the Tax Cuts and Jobs Act.That moved the bonus depreciation percentage to 100% from 2017 to 2022.In 2023 it went down to 80% and it’s currently at 60%.Depending on who gets elected again, 100% may be back on the table.Only time will tell.We know that the US government wants to incentivize more development and ownership of RE.They want Americans to continue to build and maintain our physical world.That’s why real estate is one of the most tax-advantaged assets in the US.Depreciation and bonus depreciation for RE are very positive and will likely continue in the years ahead.

MLS has it as a single family residence, 3 bedroom, 1.5 baths (actually has 2.5 baths), approx 1500+ sqft, 9k+ lot size, 2 car garage, back yard. 

Second link is a similar size, albeit 10 year older home, in Setagaya Ward (a very desirable neighborhood), but still "only $1.2M. https://www.homes.co.jp/kodate...https://www.homes.co.jp/kodate...(2) Age. 

So if they buy a condo for $700K as part of a 1031 exchange what is the portion they would have to pay capital gains to?
