I'm sorry myiysis, but any appraiser that is going to shoot from the hip and give you a value on this forum is going to get burned at the stake and rightfully so.
Because we are licensed to give opinions of value, we are held accountable for those opinions. If I told you I thought your home is worth zzz dollars, the appraisal board could ask to see my file. If I don't have a file backing up my opinion of zzz, I'm in trouble.
Personally, if it is on a rented lot, it sounds like personal property to me. Most of us don't appraise personal property. Go to craigslist.org and you might be able to find somebody selling a home similar to yours on a rented lot.
