One thing to be aware of is how a manufactured/mobile home is treated in bankruptcy.

I got someone who came across my ad on crigslist and would like to sell there manufactured home and just the manufactured home any ideas

Asbestos and mold is a lawyer manufactured crisis.  

I have no idea what your layout is but this would be much easier and cheaper to do.If you do this addition look at doing it with a modular manufacturer.

It depends on the manufacturer and the toilet model, the are differs a lot.

There are several manufacturers that offer overlay products.  

Some manufacturers are starting to make vinyl plank in thicker pieces so it snaps together easier (more like laminate).

Around here, we have a couple of manufacturers of generic thermal pane windows and can buy them cheaper than Lowes.It's not rocket science installing them, and we found someone to remove the old windows, haul them away, and install the thermal panes for $50 a window, about half of what some others wanted.One caveat, I had an energy consultant with our local utility company come out and do an energy audit, and he said if you've already got serviceable windows it's not cost-effective to upgrade to more than storms - and this is on my new personal residence.

Just one other caution when buying equipment online, most HVAC equipment manufactures void the warranty on equipment sold on the internet.

another problem is the obama law, where you can't kick out renters that have a lease, renters have figured this out and are manufacturing long term leases to foil reo lender/trustee sale buyers efforts to take possession after sale.
