The washer is metered (hot water heater + electricity) with the floor 1 tenants, the gas dryer is metered with the floor 2 tenants.

-------------------The market is hot for wholesalers...so they're pushing thinner deals and some investors are biting because they're speculating on appreciation. 

As @Dylan St Jean pointed out, duplexes are limited in number and hot when they pop up.

Additionally you are going to have to think about insulation (architect can give guidance on this) -- a converted attic will get extremely hot in the summer.It then comes down to costs of construction versus rents.

If your looking to make your first wholesale smoother(i.e by finding a hot areas for investors).

If your looking for great cash flow we have some amazing middle class neighborhoods that rent like hot cakes.

Really important to note that the marketing in a hot market can make or break your business. 

However, a somewhat hot opportunity sprang up recently, and I'm wondering if it's something I should go for.

We've got extreme hot-cold cycles that wreak havoc on our homes around here. 

@Mohammed Rahmanthanks for replying.my strategy would be ANYTHING that's valuable... an off-market smoking hot deal -- whether that's wholesale, sub2, seller fi, looking for development....i'll do whatever needs to be done...
