I've always worked for myself and didn't have a ton of support so I was not able to prove my income for quite some time due to doing my taxes wrong or not understanding how things work.

Also considering live and flip, or make our first home we buy an opportunity to increase our income as well (renting basement or part of the unit).

I think a big missing piece from the puzzle is where are you at personally with your income. 

@Ali Mol In a lease-to-own agreement, the $1,666 monthly credit should be treated as a liability (deferred credit) rather than rental income, as it is allocated toward the purchase price.

One unit is occupied by a low-income senior not on the Housing Choice Voucher program and paying well below market rent.

Would it break fair housing laws to say we are not willing to work with the program since it's not a source of income and they pay on their behalf?

Markets there are growing rapidly while still offering competitive entry points for solid passive income opportunities.Hope this helps, and best of luck with your investing journey!

But I don't think my house fits her budge since she is really struggle with rent payment although my rent is below the market (I do plan to raise my rent gradually). 

It can make more sense to do PML's in the IRA instead of rentals, particularly if you use leverage since the IRA will incur UDFI on that portion of the income derived from the mortgage. 

I know I made a lot of mistakes here, and if I could go back would certainly do things differently.Key facts:• no written partnership agreement • In business for 1 year, with 8 total combined clients• 2024 total income $29,500• No shared business property or initial investment.
