As a side note, I find that the background report isn't as exhaustive as I would like.

This is however not an exhaustive list.

Frequently they are the ones that the Counties end up with.When you exhaust that list looking on GIS systems with lot lines show odd unbuilt parcels.

The only tools I could think of are google and facebook groups however I don't think either one is exhaustive or efficient.

@Russell Brazil,I understand your point about DTI, but I was thinking more about the fact that we would exhaust a significant part of our savings to buy the multi-unit first and would likely have to save extensively for a couple of years in addition to what we might cash flow from the multi-unit to have enough to buy our single-family home next.

@David Falsdefinitely do not exhaust your savings. 

The revolving door of 3 month leases on renting out the 4 bedrooms is exhausting. 

Of course if there is a real problem, it needs to be addressed regardless.Make sure there are operating exhaust fans in the bathroom and that they use them with every shower.

I haven't reviewed the depreciation schedules with my CPA, but I suspect that has all been exhausted.

Maybe because collectively we have 30 years in the tech industry and WE ARE EXHAUSTED OF THE GRIND AND BEING OVERLOOK FOR CAREER OPPORTUNITIES!!
