If this area was used as a dump it should not be that difficult to find the records.

Money is money.Most of our properties are in a Solo 401K, but mortgages there are difficult due to the non-recourse requirements.  

So I would accept sub 500 in a market where finding good tenants were difficult. 

@Mike WoodI should have clarified - the $66/ft cost is the builders cost - he only builds for himself/partners as far as I know.I'd agree after analyzing more that it would be extremely difficult to get to the $50/sq ft # - however I'd think it wouldnt be impossible.My thoughts were if I could get it in the high $50s to below $65/ft or so you are in the project less than it will appraise for, can lease out, keep the property for 5 years for example, sell each side of the twin home as a possible exit, or sell the investments to others at near retail pricing thus recapturing the equity you created.  

Have people that used this found that this increased monthly mortgage payment made it difficult to obtain their desired cash flow?

It may be possible to set expectations and have low income tenants pay less hands-on, but it is a consideration.More difficult to screen applicants.

Getting 4 people to live together can be difficult, but probably not as hard as it seems.

If they crack down on you, they can make your life difficult.

How difficult is it to obtain? 

I would like to start purchasing at auction in King County, WA and am finding it difficult to figure out where I can find a list of properties coming to auction each week and their starting bid.
