My suggestion is you use FHA high LTV loan to purchase and house hack a detached duplex that is in need of some TLC.  

@Zac LindquistThis might not be the best strategy to use at the moment since there are so many obstacles that would need be over come in order to arbitrage now.

One of the obstacles that I am more than certain I am going to have to overcome is finding 4 plexes that are 100% occupied.

They are detached houses.

I am pricing what it would cost to build a detached 1 or 1.5 car garage on a home we are flipping and was wanting to see if you have done this on a flip and what it cost you as well as how did it impact the ability to sell the property?

Says we have detached garage.

One of my rental properties has a two car detached garage.

These are great points being made about the historic commission and obstacles to renovation.

I purchased my first home for 3bed 2 bath 1404 sq/ft ranch with detached 2 car 96k in a B neighborhood 45424, put 10k into for reno (all DIY) with a presumed sale tag between 125-130k sale/ 950-1150 rent per comparables.

We are not ruling out detached houses, but when we look towards houses, we are looking more turnkey.We currently have been looking all over Denver metro to get a feel for pricing and rent ratios, so we haven't narrowed down to a specific zip code quite yet.
