My question is can I still foreclose on the property this year.

The son lived with him, was a co-tenant on the lease, and was the main person making the rent payments.

The mother has continued to pay the property taxes and has kept them current.

Hey Connor, I'm also in Lincoln, NE and would love to meet up if you're open to that. 

I'm Joshua, a new wholesaler based in the Bryan-College Station area.

or not worth the extra money?

Save yourself the hassle and avoid these common pitfalls no matter how much you like the name or "professional" you believe the entities may appear.  

The lis pendens will be removed once the house is brought up to code (demolished or rebuilt). 

Without responding with respect to your zoning and what is allowed locally, I will discuss what is allowed on state level because i believe it will allow what you seek.In 2025 SB 1211 (Skinner) – Multi-Family goes into effect allows an ADU (I think it specifies detached but question if that is a requirement) for each legal non ADU unit up to 8 units.  

I tried looking for a somewhat relevant forum to post this under so this is where i landed.
