It happened with me and it was CL contacted him he never responded and deleted the Ad surprisingly he was put an Ad as REA.  

I have been tryin to get this condo sell on a rent to buy lease but craiglist is not working that much. I cant use zillow since im not the owner. Any suggestions will be  appreciated

They are not the occupant, you do not need to comply with any needs of non occupants following ADA.

Some of the rules seem a little unrealistic (like requiring we have ADA-compliant ramps...in a lake house...) but more troubling is that the township requires STR owners to submit an application that the board must approve, and then that must be renewed/reviewed/approved annually.

If they have not confirmed an hour prior to their appointment, I send this text to their phone (which was required as part of their contact information I required in the response to my ad):As I had requested in my email, you have not yet confirmed your apartment showing for this evening, scheduled for 7:00pm.

ADA has been around longer and actually does have some rules, but they are still incomplete when it comes to residential rentals.

My first thought was to build a small multi-family, I was going to bring some friends into the deal to ad a network for fundraising, etc, and or potentially get plans in order, and find someone to sign to the loan, and give a down payment for an equity stake.I am young with very little capital and am in need of some advice to either affirm my beliefs or point me in a different direction.

As for the rehab, I agree with @Eric Greenberg this is a very heavy lift and depending on the area it may require things like a sprinkler system, alarm system, ADA accessibility, high voltage power, and several other things that can easily blow up a budget.

@Altaf EssaniHave you looked into this as I believe you may need to get special permits, confirm it meets zoning requirements and make sure the entire home is ADA which most homes are not as countertops are lower, light switches, no cabinets below sinks…

You also must know difference between a pet and assistance animal or emotional support animal and act accordingly to the HUD, ADA  and other applicable laws and rules.
