I think this is going to be very difficult to find for under $250k especially in Summerlin. The only homes that had small guest homes (casita's) as options were built on larger lots and were usually upscale larger homes. They were typically available in 2000 sq feet or larger homes that sit on large .20 acre or larger lots. I know a home that recently sold in my neighborhood in Summerlin with a casita and it sold for $380k. I did a search and could not find anything priced under $339k right nowand this had a attached casita. I do not know of any homes in The Lakes that were offered with casitas at all when they were newly built by the developers. So you would probably need to find a home that had one added after the fact. The majority of homes in Summerlin do not have a large enough lot to fit a casita.
You can find this combination in other areas of the valley with no problem. I looked at a gorgeous home with a casita in Centennial Hills area recently that was priced at $244k.
Let me know if I can be of any further assistance.
Would a separate bed & bath in the same house work for your situation?
