We just wall off the stairs connecting the two levels.

I am always happy to help out new buyers or really anyone that others might feel are "wasting their time."

Gut demolish the walls and floors and plumbing and electric, but keep the foundation untouched?

This will be especially effective in places that don't allow gas for new construction.Energy retrofits on rental housing is largely a waste of time, particularly in markets where more housing is desperately needed.

If you want to use them for one of the services they provide that does not seem like a waste of money, but this type of company is not what I thought you were talking about in the original post.

When I went to look at the units I discovered one tenant had tin foil all over the windows and walls.

It has been a functioning ADU for 6 years and there were no modifications to the exterior and only a gas line added for a stove and dry walling up and doorway in the interior.

A major portion was eroded into the water way which is passing thru the corner and we may need a retention wall, approximately 150 feet.Phase 2 is also another 2 duplexes and each unit in all phases will be 1800 sq ft. 

Would I be wasting my time ( and lender’s) by reaching out to them this early?

The house has a detached garage with an attached studio (planning to reno & live in it).Currently renovating, but need help determining if the kitchen wall upstairs is load bearing and if I can remove it.
