. $66,763.What is his basis?

This is what the OP said:We're changing our plan for the property in 2024 and plan to rent it out for two of the summer months on a <7 day basis, but then also use it for a month ourselves.

Whether it still makes sense will depend on how much you can defer vs. the basis.

One workaround could be keeping a separate spreadsheet to track your adjusted tax basis accurately and only using Stessa for operational insights.You could also reach out to a cpa and see if they have a specific recommendation for software to use.  

Your basis in the entire property will be divided into each of the 6 units. 

They will want to pass on the stepped up basis to their descendants and you want them not to. 

I would use an experienced broker who can shop around and help you compare best terms on a National basis.

.- If you hold a rental until death, you can pass it on with a stepped-up cost basis, limiting captial gains if then sold (limited by inheritance tax limitations).Too many newbies on this site trying to replace their day job income via "passive" real estate investing w/o digging deep enough to understand how it really works.

Quote from @JD Martin: I would have to see actual data on a median & value adjusted basis to believe that OK is anywhere near Fl on a dollar for dollar comparison.

Since there is a co-owner, you would have to purchase the property and it is really hard (if not impossible) to pull a HELOC as the basis for the purchase (since it is not your primary residence).
