Many of them are looking for 'move up' homes to accommodate growing families and improved lifestyles.

Interesting you say that because in my area it seems furnished Finder folks are more interested in even smaller accommodations/ rooms because I see many (like, a loooot) looking for places <$1200.

This may not serve as direct competition for you with a house that can likely accommodate a larger bedroom voucher, but could mean more challenges for the 1 & 2 bedroom landlords given the new construction inventory will likely be viewed advantageously by the voucher recipients.

For myself, I work in the Metro DC area so I knew that buying there was out of my range so I looked into a market close by that can both accommodate my lifestyle and add value.

Personally, I came up with the idea that I should build a detached ADU on my current rental property (the property has enough square footage to accommodate this project).

We rent units to rent out as service accommodations.

Each jurisdiction has different requirements for permits that the website likely won’t be able to accommodate.

Reasonable accommodation may include waiving or varying pet polices and fees to allow an Assistance Animal.

I'm struggling a bit to put together a comprehensive approach.

One website that is pretty comprehensive so far is: http://www.paradigmlife.net/infinite-101/Let me know what your thoughts are on this.
