Many people get stuck in the preparation stage and take years to get started. 

@Tammy Vitale The stuff on top of the AC is dropped mortar from when they spread it back into the joints, excess falls.Also, I don't *think* they'd lie to me about it being new, but I do know that I told them about the AC units in the basement that they could use if they worked (AC units are not included in the lease).

There is 500/month in excess of monthly costs with the rental unit, but there will be repairs/Cap Expense/Vacancy and property management to account for.So you in the house hack scenario your cost should will be 465/month less, plus you will get the tax advantages of a mortgage and a rental property.

Together with me on the stage are 2 lenders - a hard money lender and a conventional mortgage lender.

Hard money lenders may also finance your rehab costs but their rates are higher (10+%)You will most likely have a personal guarantee on a loan and because of that banks will want you have liquid networth in excess of the loan amount.

I'm always accepting excess shekels.

...There will always be excess drama with either of these two - so you should reconsider that line of thinking.  

When you invest in real estate, for example, and want to maintain reserves, some should be in either cash or a comparable asset such as a money-market or CD, but you can easily put excess reserves and earnings from real estate into traditional stocks, funds, etc. as well - it doesn't just have to sit there.  

If you don't have proper legal structures in place to protect your family against adverse risk and shield your excess equity, don't get into any risky venture.  

So I would guess it actually won't be worth more thus this is really a zero sum game for you at this stage.
