In RE we traditionally have done brrrr and STRs.  

There's always the traditional sub-metering option if you are going in and doing some extensive work to the property as well but I've found that to be prohibitively expensive on my properties so far. 

I don’t know about the Louisville market, but if you have to pay a bit more for the property than a traditional single family, it should be outweighed by the fact you will have a tenant paying hopefully well over half of the mortgage. 

Leveraging creative financing methods like hard money loans, private lending, or partnering with investors can also help you secure deals when traditional financing is delayed or limited.

Depending on the property's location, it could perform very well as a co-living asset (3x of a traditional rental).

Weigh out the Pro's and Con's between Traditional, Portfolio, and Non/QM like DSCR. 

traditional How did you add value to the deal?

Financing the deal with cash and a loan from your brother helped you avoid traditional loan costs, which likely benefited your margins.One key lesson you’ve pointed out—always buying low and, if possible, getting an inspection is something that can save a lot of time and money.

Traditional lenders in this industry won't fund you on a purchase of a SFH that has leases for rooms and the building will need to be in your LLC name which means a primary bank won't lend you either cause of that and cause of your employment status.You have a real chance to start.
