Do you have tips for structuring short-term leases that protect me as a landlord while accommodating their needs?

My unfair advantage is that real estate is my job I have made a few different businesses out of it.

I won’t sugar coat it when I first got in I didn’t realize the over head cost to run a business .

There are mortgage recast calculators online or you can reach out to your lender.P+I payment will go from 2155 to ~1800 given the numbers you provided.

I'm currently working with an estate planning attorney and she said she said we could put the LLC in the Trust but said she was not the best person to advise on the pros and cons of that and that we should talk to a business law attorney.

Your taxes are none of the ex wife's business and this would seem to address your concerns.I would also put her on notice that future requests for financial discovery will be two-way and if a discrepancy is seen in the other direction you will seek support from her.

I would tend to agree with the other CPAs typically.The 500-hour test is one of seven material participation tests used by the IRS to determine if a taxpayer is actively involved in a trade, business, or rental activity. 

Quote from @Francisco Solano: I suggest you ask a business attorney in your state for this basic template.

I run a full time flipping business, right now i am able to do 2 homes at a time.

We want to plan in the most tax vantaged ways (which includes keeping future AGI as low as possible) and open to new-age and creative concepts.Respectfully ask to keep discussion to topic vs. selling one's self or services seeking new business.
