1.) Kill LendingTree by creating a service that actually lives up to their slogan "When banks compete, you win". In reality, signing up with LendingTree will just get you aggressively harassed by "Boiler Room" salesmen offering terms worse than whichever bank holds your checking account.

2.) Anything to simplify / make comprehensible the mountain of paperwork that accompanies every transaction around mortgages.

3.) Online payment services for rent, HOA fees and whatnot that aren't painful to use. As a rule, the existing services for this are expensive, ugly and dangerously unreliable.

4.) Home / Apartment search that does more than just dump information on you.

The typical search offers little more than a price range and a zipcode.

I want to be able to provide your search with info about what I do for a living, how old my kids are perhaps a few things that are important to me and get recommendations that consider all of these things.

I don't need to be told about the options in the places I know about it. I need it to reveal the ones I haven't considered.
