Some good info for a base of knowledge and conduct your business legally but most not very useful.Focus on systems to serve clients at a high level,  your sales skills, negotiation and ways to get leads. 

They were supposed to be starting the new job a day or two before I served an Ohio 3 day eviction notice.

They will know the proper way to serve notice and evict.

If you haven't served and don't want to bring 15% down to the table then FHA will be your only option.

You can sue the tenant but serving them will be the difficult part. 

@Jamie Derasmo on question 1, in this market if you want to keep buying you kind of need to look at everything, at least everything that is a size of a project you're willing to take on (which it sounds like this one is).On question 2, it really depends on how good of a deal you're getting, whether the numbers work to allow you to use hard money.

When I lined up my PM, I got a file (large one) on every area they PM in, that showed me the rental comps broken down on a map (critical...zip codes alone are useless) for different sizes of properties. 

Then check recent comps for the sale of vacant lots in the area, similar in size and location to yours, with the same zoning. 

Houses that look very similar on paper (same neighborhood, style, square footage, year built, beds and baths) can have very different market values depending on things like interior light, flow, ceiling height, privacy, yard space, neighbors, curb appeal, master bedroom size, kitchen counter and cupboard space, parking options, driveway slope, proximity to noise or businesses, parks, schools, etc. - to name just a few things.
