@Joshua Tikal College rentals are not something we specialize in but the experience I have had from managing thousands of rentals over the years is that everyone starts out wanting to provide good housing options for the general public but lose sight of the fact that this is a business and please run it that way.

BTW the Sheriff doesn't sell most foreclosures in Colorado, it's the Public Trustee. 

If you don't advertise it publicly but offer in private, you don't promise anything.If you do offer the premises for rent publicly, it has to be compliant with Fair Housing law.It's a slow time in rental business and if you never find who are you looking for, are you willing to take on financial losses because of that?

This includes Public Housing Agencies and Multi-Family owners.

I am making no judgments, but it usually takes quite a bit for someone to get this public with a dispute.

While many events are for members only, I believe the bus trip is open to the public, and they have at least one free event per month.Regarding your capital, you have more than enough to go directly into multi family which would allow you to build passive income faster.  

In addition, as a licensee, I am able to see a lot more detail then public remarks.

Public data sources or paid lists? 

A tax lien state you are bidding on properties knowing that the large majority of properties will get redeemed and you will get a small percentage of properties.Most wholesalers buy lists of addresses and send out a mass mailing trying to connect directly with a motivated seller before their property goes to a public auction or gets on MLS.

The key is simply act ethically and professionally in everything you do, disclose anything that needs to be disclosed, and hold yourself to a higher standard than even the public would hold you to, and you will be fine.
