They go to treasurer's site to get current owner name and mailing address.

Good Evening,I'm getting started in real estate investing here in the treasure coast.

Many/most municipalities categorize them the group. ie, when you look it up it will say mobile/manufactured for the type of structure.In my case, the tax valuation on the property is ridiculously low and the Zillow value is also about half of what I think it's worth.A modular home is very different from a mobile home/manufactured home/house trailer, etc. ie, they're not on a metal frame, don't have that mobile home look with battens every four feet on the walls and ceilings, etc. and in my opinion are as good or better than most stick built homes.
