Keep in mind in most mortgages you can make pre-payments with no penalty.

Another option is to make sure you're pre approved for a loan amount to buy in your desired area, if you're not pre approved maybe ask a family member who is not planing to invest or request loans in the next 5-10  years to   co sign on loan.  

This is a great start to get you pre-approved and this way you'll know your buying power and you can move forward from there.Also check out my interview on the Joe Fairless Show, the link is on my profile.I hope this helps and have a great weekend.
