Our property is zoned for 2 houses so currently researching if it would be best to build a garage DADU or full house (hpr the property) for two separate rentable units on one property. 

@Anthony Dooley  well obviously we need shelter I am not advocating living under a bridge .. the reason buying a home first for many is a logical step is as much how our financial system works first time home buyers can get into a home with an FHA loan or a USDA loan and there are all sorts of down payment assisstants  etc.. as you know your a realtor.So they can get that home.. and in low value areas if they just put the amount they would pay for rent against their mortgage they would own the home free and clear in probably less than 10 years.. with next to nothing down.. so you have not tied up anything but one loan slot.. not much cash and it does not hurt your DTI.Now if you try to start in investments first you need much larger amount of money down.. you have no experience owning properties.. so financing is tougher..

In TN for example(in most areas with zoning laws) the DADU must be minimum 300sf and max of 700sf, must match the style and appearance of the main structure, minimum lot size of X, and so on. 

Way to find a slot where little to no products are and offering something that others do not.

So I see this as a perfect SLOT Deal.  

I cut slots around the legs of the appliances and just slid it under each one. 

Given the recent slot-home initiative and sentiment (like yours) against such projects I know of no variances granted in the last 5 years for any slot-home project in the City and County of Denver.

You should always looking into single family houses or multifamily, as there is an actual land that you own and potentially build ADU/DADU in the foreseeable future.Also, the beauty of FHA is that it allows you to put 3.5% down payment to invest in 1-4 units.

Seattle now allows 1000 sf of ADU and 1000 sf of DADU on all City lots, space providing.

Last year we moved out of our FL condo and moved into a 3/2 that has a DADU in the rear of the home.
