It's a fine business model as long as you don't mind your tenants paying fees for your use of the software. 

Too few details to answer (Of course this varies county by county, all questions could be answered by reading the (zoning)/building code and/or clarified with a visit to the county planning office).but some clarifications because: lots of things are "tiny homes" but what you describe small houses "on permanent foundations" needs to be clarified , tiny homes could be:-stick built, see below. check your county code/planning dept-stick built cabins/recreational, a specific zoning and potential occupancy/etc restrictions but worth looking into where the zoning allows for it -hud manufactured homes (smaller singlewide perhaps 400sq ft 600sq ft minimum)-non-hud park models (on axles), ansi standards- other "RV's" built on a chassis:  organizations, state agencies, etc - will certify factory built (or sometimes inspected professional built) tiny homes on chassis - to whatever standards ansi, riva, dot/ l&i?

One time deal is not always a great business model.

If the tenant responds that the problem still isn't resolved, then the system asks them to send a picture of the label with model and serial number.

But, happy to make an intro to a woman I work with that runs a 'boutique style' staging company -- She is also a wealth of knowledge on the topic and I'm sure would be happy to shed some light on this for you! 

We've spoken several times with an attorney who specializes in this area of law, and he's assured us that our flat-fee investment club model is well established in the law and that we're not selling securities.
