One thing I continue to think about is how valuable 2-4 unit properties are becoming, and will continue to be, since Fannie/Freddie took the income restrictions from the 5% down conventional loan option for house hackers. 

I just don't want to run into any problems with the lender when I am about to close on the house.

They even sent someone from the city to the house to tell us to stop operating it as a STR. 

We are somewhat handy and would not mind fixing up the house while living in it. 3.

Seems to be decent on Airbnb with the guest house/ADU units with all the hospitals nearby.

From my experience you should expect a 10% to 15% of gross revenue for repairs/maintenance. 

Or enter "for repairs" and take photographs of expensive new stuff for court...but they may be paying down credit cards.

One of our parks is 60% POH and in my experience the only way that park pencils as well as it does is to get through all the major repairs, get the homes 'right' and then keep them 'right'. 

Best of luck on your continued journey, HELOCS can be a great tool to utilize untapped equity in a house.

Overall, it's going to be up to the state and local governments to enact changes that will affect the local housing markets.
