I would assume the funds could come from any account since you are allowed to go into joint ventures, etc. hope this help some. 

Fortunately, when investing in real estate, there is a range of options available for garnering capital, which include equity and debt financing, investing with family or friends, joint ventures, starting a blind pool fund, and seller financing.

Is there a tax return generated for/by a joint venture?

There happened to be a joint that exposed with this section of pipe. 

I now have Legal advise from attorneys, Legally prepared documents for my business, Contracts, Joint Venture agreements, LIVE one on one ZOOM calls with active community leaders helping me succeed, Underwriting, Lead generation, Acquisition strategies...once again, the list goes on and on. 

IRS - Topic No. 701:"If you have a capital gain from the sale of your main home, you may qualify to exclude up to $250,000 of that gain from your income, or up to $500,000 of that gain if you file a joint return with your spouse.Publication 523, Selling Your Home provides rules and worksheets.

Because we file jointly, and we use schedule E’s, there really is no reason to keep them separate.  

Taxes would be simple as we could file as a qualified joint venture.option 2: Open single-member LLC with myself as member and have LLC own the property.

Does cost segregation make sense for STRs if owned jointly with a 50/50 partner?

Thinking through different exit strategies which include 1031s (traditional,) outright sales, switches into over vehicles (ie. funds such as Realty Mogul, QOFs, MAS that work w/1031s) etc.One scenario, overly simplistic in my mind and thinking something obvious might be getting overlooked, is pane low income.Lets say my wife and I save up funds and suddenly retire at the same time, where we would have zero w2 income and other income sources (ie. rental income) would be below the 2022 married filing jointly limit of $83 350 - would this then mean we could sell an investment property we had for over a year and incur 0 capital gains?
