So I'm going to avoid telling you that you shouldn't have driven into the ditch, and focus on helping you get out of the ditch.I'd give the deposit back and get rid of the problem on my shoulder.

The ADA requirements are very specific: doorway widths, length of handrails, amount of space on stair landings, emergency alarm in shower.

You sound like a very switched on individual with your head well and truly screwed on your shoulders. 

I checked Home Depot, they had only an even smaller width in store. 

But when spmeone comes up to me with a chip on his shoulder, well then my reaction will be defensive.  

Sounds like you've got a good head on your shoulders and are doing all the right things to educate yourself on the industry. 

I try be a dolphin swimming in company and never work toward being a lone whale taking everything on my own shoulders or being 100% financially responsible for everything especially all expenses and risks.

Which I strongly suggeest you join all your local REIAs, rub shoulders with local landlords who can help you with what areas better tenants want to live in.   

Give someone 100% and charge your points to the back end of the loan and sh*t goes awry, they are a hell of lot likelier to shrug their shoulders and say "oh well, i have nothing in this deal anyway, so, see ya lender...thanks for letting me have zero skin in the game from the get go. 

Due to the width I would need to make it two stories.
