It was all wireless and uses self adhesive back to mount.I think you can order a basic system for around $300.00

In my lease I have the following:(d) No spikes, adhesives, screws, hooks or nails, or the like may be driven into or applied to the walls or other surfaces without our prior written consent except that small nails may be used for hanging wall decorations.

Especially if the floor has a black adhesive on it like the picture above...https://www.asbestos.com/products/construction/adh...

LP=Limited Partner.GP=General Partner.LP normally has money and prefer return and GP does the work and residual return.

It worked great to remove the residue.

Sounds like the investor with all sorts of rental properties in their portfolio is a residual income investor moreso than a wholesaler.

Ozone (O3) is very unstable and harmlessly turns into oxygen after a few minutes so there are no chemicals or other residue left when your finished.

We've used a mix of laminate, tile, and adhesive vinyl squares in our rentals and rehabs over the last few years.Concrete, tile, and hardwood are all relatively permanent products.  

If he was going to flip, he may not value the residual income stream and might not be interested in a seller financed deal.Third option to sweeten the pot would be make the term shorter, say 35K purchase price, 7-10% interest 30 year amortized but ballooned at 24 months.  

Seems like the first installation method that requires no adhesive and the claim that "planks are extremely flexible and self-level above the substrate to create a flat surface, even over imperfect subfloors, making for an exceptionally easy installation" could be an issue when the subfloor is not level.
