I'm assuming these organizations would pay far below market value for land, but there are obviously also some significant tax benefits that may potentially offset the "lower-than-market" valuation you may receive when selling to them. 

Do you get the value of it back if you sell or does it increase the potential rental income?

CMBS loans are underwritten based on the income-generating potential of the property rather than the borrower's creditworthiness.Mezzanine Loans: Mezzanine loans provide financing that sits between senior debt (typically a mortgage) and equity in the capital stack.

Any deflection or uneven seams between sheets will lead to cracked tiles on the future.

@Jacopo IasielloSelling would probably reduce stress but the only thing that is stopping me is FOMO of future cashflow/appreciation.

It’s a bit of a learning curve, but can be worth it for the potential benefits.As always, chat with a tax professional to make sure you’re on the right track and taking full advantage of the benefits.

However, we're having doubts because: 1. we wouldn't be able to afford the PITI on our own for longer for >6 months without the help of rents, so we're depending on the house hack to be able to afford this house, but not sure if that's a bad thing or not and 2. not sure if this house is too much house for us financially and we're in over our heads about what we can afford.We've been super excited about this place until we realized the issue with the illegal basement and now we're overwhelmed with the thought of potentially not even moving forward with the house.

This is how I bought my current primary home for $500 out of pocket that now has several hundred thousand in equity & a HELOC for future deals.3. 

Wall Street thinks there may be, possibly, potentially, feasibly, conceivably… a slightly higher chance for an interest rate cut this year.

Multiply that by 4-5 (for the 20-25% down payment) and you will know the size of your potential maximum purchase.
