You only need a place to track tenant information, payment history, maintenance, etc.

e.g purchase price is $2m with a down payment of $500k.

I don't think payment method has any bearing on giving a 1099 or not? 

Non-residential will be a problem for most investors on this website.Furthermore, 179 expense is an issue as you need to have positive income to be able to use it.

Do you know if it is possible to do the cost segregation and bonus depreciation if I non-resident of the US?

It's beyond unlikely the bureaucrats who mishandle our boondoggle of naturalization are proactively concerned with internet postings concerning incorporation details for non-green card holders.

I have read about stand alone policies that promise to pay if the tenant defaults on rental payments but I have not ever written that type of coverage.

Financially speaking, I'm still saving, but the goal is 50k saved up (all costs: closing, fees, down payment, portion of rehabbing costs) by this summer with my fathers help on the cash all while I continuously save 50-80% of my work checks to fund for rehabbing this property and I work off my second job and "survive off of that."

Agents would unfairly lose out if this scenario became popular.In due time, I could see this happening for NON-pre-sale renovations, e.g.: •Curbio develops a strong reputation for quality and efficiency•Homeowners are attracted to Curbio’s ability to get things done efficiently, reliably and cost-effectively (no nightmare renos that go on forever)•Curbio continues to enlist realtors as strategic sales partners, by devising a referral commission program for them, to mitigate channel conflict•Curbio maintains sufficient decision-making control (e.g. project types; material & appliance options)•Homeowners are given sufficient preference choices within strict guidelines (e.g. color palettes; good-better-best options materials)But I suspect one of these two growth scenarios for Curbio might happen beforehand:•Expand current offerings to owners of rental properties•License technical infrastructure and processes to qualified contractors

Agreeded with the first 2 posts, I've only experienced this once to have damages/ missed payments exceed security deposit.
