We called this the "retro room" because of the 2 layers of awesome wall paper.

This stuff appears to have lifetime residential, 10 yr commercial, and wear layer 3 times as thick.

The rehab costs have far surpassed our budget due to some masked  issues(missing copper lines in walls, dangerous wiring almost throughout...all covered with sheetrock) Also, the city is requiring us to pour new approaches at "multifamily" thicknesses; about $9k worth. 

Can they just pour a new layer on top of the old layer?

NO Candles,, that's just trying to mask odor and candles are dangerous.6.

So, to answer your question, whether to paint or refinish or put a layer of some other flooring (e.g. laminate or plank vinyl) on top depends on the style of the house, the condition of the wood floor, and the type of wood.  

It has .5mm wear layer and comes with lifetime warranty (whatever that means).

Some mask themselves as HML but no more than a broker.

In your mind you have created an extra layer of litigation protection but to accomplish this you have hovered around mortgage fraud & added a risk of the loan being called.

It's all about layering yourself so that WHEN the deals come, you can capitalize on them (no pun intended).
