-------------------------------------You are double dipping in the second scenario, because you divide the entirety first and then take the obligation to you entirely out of partner's share.

Just to have an agent rostered on my team before they produce a dime, Im out of pocket $12k per year with technology and insurance costs.Your team owner isnt getting the entirety of the amount either.

@Ben Cochran, The entirety of your sale has to go into the purchase of the land and building if you want to defer all tax. 

I have talked with tenant B multiple times through ought  the last year as he has been behind on the WATER and SEWER bill the entirety of the lease.

First let me explain my situation, a bit long but I hope that's okay:-Bought a 3 level townhouse in July 2020-After a few months of remodeling, I rented the upper 2 levels in November 2020 while I lived in the basement of that same property-I had to live in this property for 1 year because the loan was an owner occupied loan that required it -I lived the entirety of 2020 and 2021 in the basement while I rented the upper 2 levels-Just not long ago, I finally rent the lower level basement in April 2022-I have tax returns showing the rents received from the upper 2 levels for 2020/2021 -My lender says if I want to have more purchasing power for my next property, we can use my rental income, but instead of just using my upper portion of the property,  (showing my tax returns for the upper levels (2021)) it turns out I could use BOTH the upper and the lower, which was great news, BUT a "rent schedule" needs to be done to INCLUDE the lower level.

Is anyone aware of any lenders who might consider allowing the borrower to prepay the entirety of the mortgage interest in the form of discount points? 

If the credit is applying to my personal tax return, I would think that it applies to the entirety of my income.

I am not sure if opening an LLC would be a possible loophole in my situation, or if my best option is to have my mother take a mortgage in her name and make the payments for the entirety of its duration.

Many do not want to be responsible for understanding proper filing and withholding requirements.So looking at that, it really comes down to having a tax ID number to tie your investment to, and it must remain viable for the entirety of the investment and all K-1s being issued.

To your specific question - "the first year" (or, more accurately, the year placed in service) applies not to the house in its entirety but to each separate asset.
