My fiance and I (soon to be married) have a household income of about $100K combined, plus we will be collecting rent on one unit starting January 1, so my hope is that sometime within the next 12 months that will be sufficient for financing.

Did you know that special needs housing, where you rent out rooms separately but with shared kitchen and dining space, can (if you set it up correctly) provide greater income than renting to one household?

The irony of Dobb Frank is it turned into a fairly household name but it did so under a very simplistic lack of in-depth understanding of what it is.  

My pre-app was for $200K but I figure I dont want to max that out because I'm maintaining a household here where the exchange rates are out of control.

Have an agent assess your risk, if your house holds 6 lives living in there, $1M won't go far, neither will the umbrella and make sure you are with the same company if you have more than one policy.

I currently rent, and live in an extended family household.

There you can search a given zip code, then view heat maps according to all sorts of parameters such as household annual income, median rent, etc.

They offer a tremendous value for the dollar, in which households can live in nice areas for a fraction of the cost of stick-built homes.

Excellent schools, centrally located bedroom community, top 3% household incomes, etc, keep the values stable in this little pocket of suburbia.

Since you are talking about selling to help with household finances that tells me you want to sell to pay the bills.
