It is a good idea to put section 8 accepted in the ad.  

I've been been going over all the ADA requirements, but could probably go further in comfort department with simple things that might make a world of difference.

Here are is my advice if yo wanna try outHave a Professional website direct to the point REMEMBER first impression is the last impressionTry to create engaging content and share on your facebook pageUse a Professional profile picture and nice cover imageRun PPE ad and target your the group of people you wanna target, interest, as well as locationLet it run for few days make sure you add your facebook pixels in your website before you run ads that will allow you to track what happening and also add Google analytic to your websiteGet a designer to design nice ad image for you LESS TEXT MORE CREATIVE.Run it for few days and keep tracking the process and after few days start a retargeting ad as well with it so people who visited your website showed some interest and than left retarget them.Above tips were simple and to the point.

I have a disabled man wanting to move into a one bedroom unit. This is a 1970's building. We do have safety bars in the bathroom but no other equipment. We also have 40 parking spaces for 70 units in our parking lots ...

I thought this was part of the federal ADA which would mean that this would be true no matter the state but perhaps I'm wrong.What I'm learning is that it is always best to treat tenants, vendors, contractors, etc as calmly and even handedly, as possible.

I have found it harder to find someone to build a four-plex because ADA laws come into play.

And if the home is designed with them in mind (ADA compliant bathrooms/kitckens, elevators for a multi-unit, etc.), it just seems like a good way to go.

We were thinking our best option would be to sell on land contract both ad a deal or the house on contract and sell the land next door straight up to someone but to who?

But after considering these other factors (bathrooms, hallways,  ADA compliance), I am concerned that I'm unable to provide what they are asking.
