@Marian Freshour 7 years is usually a safe and prudent amount of time for those type of records. 

Follow these tips and you'll probably be making a pretty safe investment.Don't buy in the roughest neighborhood in the urban core.

For that kind of interior Devore Design will likely be your best bet. 

@Gorden McFarling  Your best bet by FAR is to contact a local Realtor and get it listed on MLS. 

If you want the least amount of work but lowest cash flow (cover 50-80% of your mortgage payment), I recommend finding a house with a basement/mother-in-law apartment, and live upstairs and then rent out the basement to a long-term tenant.Denver metro has experience terrific appreciation like most metro markets, and over the last 40 years, Denver averages 5% appreciation, so Denver is a great bet long-term.   

FHA for house hacking is your best bet.  

Problem properties will be your best bets.

My brother in law lives in Canby, MN and you can rent a nice SFH downtown in a super safe area in town for less than $500.

I'm assuming when a lender is involved, they do everything in their power to make sure it's a safe investment.

The other day Biggerpockets took a couple of my posts down and I got a little prickly not because I think I have the right to say what I want on their forum, but because businesses predictably try and play it so safe and they won't even stand for the values that give them the right to be in business.
