actually the most profitable way for you to do it (it sounds like you might be single) is to rent out half, and be a minimalist; keep most of your personal belongings in a storage facility (or locked in the basement if avaliable) and just "disappear" for a few days if an air BNB customer books. 

I'm looking at a 50 unit apartment complex and the costs you mention disappear vs the insurance and the things the insurance doesn't cover.Or let's say a single or multiple collection of single family homes with a net worth of a million per entity.By the way text never gives tone very well. 

That gesture almost always relaxed the seller and the apprehension largely disappeared.

When the retail flips and all attractive deals dry up you will see investors and brokers just disappear.  

So every non-government job that exists in the city will disappear in the foreseeable future.

Furthermore, in your current situation, boyfriend/tenant could just up and disappear leaving you with a tremendously expensive situation that could take a few months to resolve. 

Hoping you will get the tenant out is a luxury that disappeared in March of 2020. 

My only caution when going this route is to understand the repayment structure should you abruptly leave he job (either on your own accord or otherwise).

Some really odd projects have popped up and disappeared.

I am on a apartment lease with a former friend and he has disappeared with out payment and will not respond to me or the landlord.
