I’m exploring the idea of turning it into a furnished long-term rental to hold onto it, generate income, and possibly return to STR when things settle down.However, I’m new to the furnished LTR space and would love advice!

.- You should have required the tenant to sign a Hold Harmless Agreement, indemnifying you against any of their claims.

Usually when I am in these situations Its me holding the money..

I agree that DealCheck (or the BP calculator) does not provide enough tools or functionality to analyze those types of transactions (yet).But I would argue that it does a great job at analyzing more traditional buy & hold SFRs and multi-families, as well as flips and rehab projects. 

Investment Info:Single-family residence buy & hold investment.

Most turnkey companies proforma does not tell the complete story and that is why is called "PROFORMA" OR "PROJECTION", they don't account for the true vacancy, leasing fees, holding costs, and Headache factors that come with a Class C and D properties and neighborhoods.Hopefully, they can help you get to 100% occupancy and sell the property so that you can re-invest in a better neighborhood and relatively newer property like 2020 or newer if is possible in that market, or just go to another market you understand better or have some kind of connection with.All the best and keep us posted on your progress.

Then listen to any podcast that talks about this (which is a lot of them).Are you looking to hold on to these as rentals?

If you're investing in real estate, ask yourself can you hold this a minimum of 8 years, ideally 12, optimally north of 20?

There is no communication except for an irrelevant biweekly blog that holds no value to me.  

Quote from @Timothy Franklin: @Trevor FinnI would agree with your breakdown, but why overlook a potential to run the 91k subject-to with a targeted 6 month hold for flip or 18 month refinance?
