I will know more on the condition of the units and the building next week, but on the surface this seems like a logical deal.

They might ask for some type of down payment just know that you have some skin in the game.

New roof, HVAC, all hard flooring surfaces (no carpet), upgraded kitchen and bathrooms, landscaping and more!

I can't see why a landlord would have any objections to this as from their perspective you are putting more skin in the game by having your future credit take a hit if you fail to pay rent and pay on time.

Your plan is supposed to be: only Offer the amount that YOU'LL pay if a Buyer doesn't surface!...

looks like you've got a little skin in the game already, that's great.What are your long term real estate goals looking like?

The idea of someone not buying a home because the paint color was wrong just got under his skin.  

The more unit, the more tenant issues... so only start with a 4plex if you have a thick skin, it's in a great neighborhood, or you have experience with management....If you can't afford a plex in a decent neighborhood, consider buying a plex and moving into it.  

Now when we look at the surface items (flooring, kitchens, paint, lawn care, etc that is pretty easy to replace but that tenants habitually destroy) vs the items that really matter and can suck up a lot of funds (electrical, bathroom, landscaping, etc.).  

Kitchen surface is their name i think.
