The addition includes a large bedroom, bathroom, and walk in closet.

Additionally, our strategic marketing efforts highlighted the property's features, attracting buyers quickly.

I also make the Guarantors go through the screening process (background checks, proof of income, etc.). 

You cannot count any non-conforming/illegal units income towards the total income for the property either.

@Tyson E Keslar There are a lot of variables to consider in addition to the roles and responsibilities that you have outlined.

You can’t live off the rental income? 

You want to make the second unit in the basement, attic, or add it on?

Also, the opportunity cost of leaving the property vacant for a year while paying a mortgage on it and not receiving rental income is much higher than what the marginal difference in rate will cost you until you cashout refi it.

Working around people isn't a big deal; most addition and major systems work happens with people still living there.
