is there a tool on this site? 

Search the BP for ADU appraisals to encounter numerous examples.

For the community development dept, you'll need proper plans (architect), site survey, permits, etc. when you're ready. 

But consumers all are on the site for free where real estate agents are constantly hawked to buy leads or participate in what is now a 35-40% referral business for unvetted leads who think they are contacting the listing agent.Their business model has always been flawed.

This is going to vary significantly depending on numerous factors.Always happy to connect 

Many of the OTAs and lead gen sites, like Furnished Finder, are pushing credit card payments. 99.9% of the time I get a message from FF saying 'your tenant would prefer to pay by credit card so activate Stripe now!' 

No, he's not an architect, he drew all designs, floor plan, site plan, etc, and we had a structural engineer design his part, and paid an architect to sign off on them.  

I'm on a call now and they same decent and honest, but some reviews on here and other sites are a bit concerning.

Best part is that it unfolds and if site prep is done, we can have a renter in in a matter of days upon delivery. 

Is there any good resource with links to the relevant sites in particular states/counties?
