@Alecia Loveless is correct--tenants need access 24/7 to their electric service panel, water and heat, assuming those are individual utilities for each unit.

I have also utilized owner financing for longer periods of time, including personal residence and 2 barrier island houses on the coast of Florida.  

I own real estate investments and I own other asset classes like stock, crypto, etc. and there are pros and cons to all of them.I will say there is nothing wrong with selling your property and utilizing the cash elsewhere.

There are actually THREE kinds of subject to transactions1- subject to existing mortgage without lender approval2- subject to existing mortgage WITH lender approval3- subject to existing mortgage as part of a seller financed wrap around mortgage.with #1 and #3 it’s in everyone’s interest to utilize a third party servicer, who collects and then distributes payments.  

I underestimated utilities in my early years, so I ensure those are properly captured (electricity, gas, water and trash).

Replacement homes will be climate hardened, smaller, functional and include consideration for the type of infrastructure, architecture and sustainable/durable materials utilized. 

Gave him 10 months free space rent and paid for all his utility hookups. 

Would you be willing to describe a bit more about how you determined your utility caps? 

I would also try to minimize expenses through decreasing cleaning costs, installing smart tech like a thermostat to control utility costs, etc.5.
