I figured if that was a sample of what the general public was going to be receiving then I was not interested. 

I had not considered that because I was imaging a deal where they purchased with a loan and the lender would not have accepted excluding issues like this.

I am at a point where I have reached a ceiling with my primary lender and need to find alternative lenders to work with.

Seems like the best case is for non payment of rent. 

But this is how I approach planning at the highest level. some additional context you can put that into land and with guidance get non recourse debt on one development deal that will change your life. there's the slow method of one at at time or go bigger for 100+ units with capital raise. tons of strategies but great points all around Scott 

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?

The lenders we have spoken to will only finance as a personal residence.

Can anyone recommend a lender or possible solutions to move forward.  

In my experience, the lender doesn't care what I do on the lots as long as I pay the mortgage.  

I always find REIA meetings great for networking with local lenders, contractors, property managers and other like minded investors who are usually willing to share referrals.
