To add to the questions - what if you you buy a property for owner occupancy (under the mortgage requirements), and under the year, have to move due to job circumstances.

I put a huge amount of weight on the credit score depending on the circumstances that lead to the score.

The areas that offer these properties have been neglected by previous owners, tenants etc.

George - I've definitely been taking the "last" approach -- letting the property sit and waiting till the Seller's circumstances change and then coming in with an offer that makes a lot of sense for me -- far under asking -- and then doing added negotiations during due diligence to lower price even further.

Heres some stats on the property at the moment:Duplex, we live in one of the units currently.Monthly Mortgage: $1,289Unit A pays $1,000 a monthWe pay $289.Once we move (Someday) our unit will bring in roughly $700 a month (it’s a smaller unit than A)A no cash pull Refi will make our property pretty decent on the monthly cash flow, almost breaking us even each month, but a cash pull would help with my debt, or a down payment on another property.I know pulling money out works for some, and not for others because of everyone’s different circumstances, but I am just curious if you guys might be seeing something I’m overlooking?

hard to say since there is no correct path, everyone has different circumstances so everyone has a different method.determine your goals, develop a strategy, create a clear plan to get there, execute.

And because I am considering doing future live-in flips (after selling this house) - I'm wondering about the calculations in that circumstance. 

Now, one way may work better than others in your area, however, if you neglect any source of marketing you may be neglecting an opportunity.

The market in Denver is changing (as it is everywhere, I'm guessing) and the particulars of the job market, housing availability, and population fluxes makes for unique and dynamic circumstances.

Whatever documents you use should be tailored to your specific circumstances and acceptable/enforcible in your local area.
