I think that the strength of the rental market here in Denver will cause people to jump at properties they normally would not consider.

go to homepath.com and see if you can find the contracts and print them up. i have not worked with many of them ( i am a licensed agent so i have worked a few deals with them, none investors so i don't normally read to much into that clause ) but somewhere in the counteract/adendum it will say when you can and can't sell the house.

Which I am told you can normally evict inside of a few months.In other cases however be prepared for a tenant who may or may not have a valid rental agreement you need to honor, or a tenant with an expired lease who a judge may provide some sympathy to, dragging things out for quite some time.

Normally you as the new buyer are obligated to honor any existing leases or option agreements. 

The final walk through is usually done a couple hours prior to the closing, so this seems normal to me.

If you go to meetings in the area there are normally multiple quality wholesalers present.

We don't need pristine, but we're not looking to put tens of thousands into it up front after purchase for repairs, just normal maintenance.-- ~75% rented.  

Also, are their repair estimates accurate or normally low?

If you average $10k per investor you will be putting in more than one investor into any asset of 'normal' size and if we approach median property values and the associated loans, you will have many.  

I do agree that this would be risky and probably not particularly smart under normal circumstance.I guess the elephant in the room is that my (job) income will go from ~$55,000 to >$200,000 when I complete training in 2017 or 2018 and this is virtually guaranteed unless the US healthcare system completely unravels.I am a bit more risk tolerant with that in the back of my mind.
