Other than comps for 3-unit properties (which are typically not furnished and operating as STRs), how would most seasoned STR investors look at valuing the property?

I use this type of system in a ten unit that I own because the cost to submeter each one was cost prohibitive I usually don’t include other items like wifi/internet unless it’s a furnished/short term rental. 

I know you mentioned doing STR, but then you need to spend another $10k+ to get it furnished.

A lot of young professionals like this area so furnishings should be modern and "upper-middle end", if that makes sense.

I furnish and provide amenities that warrants this so I do a lot of work to find comps in this particular space.  

I furnished the other unit and am sitting on it until July when the STR lottery opens. 

Condo a bit different - 7% note, but we furnished it for a MTR, and tenant is excellent and deciding to stay longer.

We only have 6 doors.  5 are long term leases and 1 is a furnished medium term rental. 

Focus on learning the basics of MTRs, including their appeal to traveling professionals and the need for furnished properties.

With your additional $100,000, you’d have a nice cushion to renovate or furnish a property like that.It really comes down to how involved you want to be and your long-term goals.
