Talking to the agent's broker is probably the first step, this is definitely a misrepresentation of material facts if they knew.

Addition once prepped: 1000 X 200 p/ sq : $200k (all depending on architecture of the home: as a more modern design with a lot of glass and steel will be much more expensive : or more expensive materials would be more expensive also. 

For example you have renderings, feasibility studies and presentation.

There are actually some decent articles and step by step case studies from people who have resurfaced their garage floors as well:https://www.concretenetwork.com/fix-concrete-cleaning/removing-embedded-oil.htmlhttps://www.bobvila.com/articles/concrete-floor-repair/

Or you can hire an engineer and have them write letters explaining quality of work, materials used etc to verify that the work was done correctly.

@Fredrick Lewis Yes, the main difference between mobile homes and regular properties such as single-family homes, duplexes, and apartment buildings are how the homes are made and the materials they're made out of.

If you go the 203k route, you'd want to get a 203k consultant in there to do a feasibility study on what the property needs, and about what it costs.

How do you have money for materials, but no money for down payment?

Then, you jump into the topic of material issues....and that's where you'll want to discuss with your agent to understand how that works.
