I went from buying multiple properties per year to doing nothing 2022. 

Nothing illegal about doing that, but if caught, the lender may call the loan due and if you don't correct the situation or pay the loan off, they willstart mortgage foreclosure.3) You could also go the HELOC route to tap the equity in the home, but the 12-month owner-occupancy will also apply AND the interest rate on the HELOC will fluctuate with the Fed Fund Rate.4) You could do a cashout refi as an investment property, but that will be at an interest rate 0.5-1% higher than owner-occupied rate.Suggest you meet with 2-3 lenders to explore your options about the above.Once you have access to funds, recommend you buy a 2-4 unit with 20-25% down. - You can buy owner-occupied, live in one unit, and fix up and rent the other unit(s).- If you're handy, recommend buying a property in the worst condition you can tolerate.

However, if you have multiple rental properties it might be impossible to claim that you materially participate 500 hours in each property.

The PM should be an expert on state law, and they should have policies and procedures in place to handle these situations.

You pay your agent at closing (think of it as an additional closing cost) Depending of the situation and of these options can be used by you and your agent to negotiate with the seller.

Not knowing your situation, you may or may not benefit from a cost segregation study. 

You can present an offer that aligns with your financial goals, but be prepared to walk away if the seller won’t negotiate to a price that ensures you’re not left in a tough financial situation.

Has anyone else encountered a situation like this?

Generally there are multiple units for each "zone" if you will when I've seen them installed.Regarding your problem at hand, I personally would simply adjust your plan to move and make your initial plan to get the current issues resolved, while costly now, in the long run holding onto the unit will likely pay off. 

I have a situation where a person I know is moving out of the country and would be looking to put their home for sale in the summer.
