I would get a conventional mortgage and put 5% down, You'll still have PMI as a monthly cost but when you reach 20% equity you can usually refi or appraise out of it (ask a loan officer). bottom line is at 22 years old you have the capital to live for free essentially and benefit from home ownership. you certainly have more buying power than $100-$200k as previously stated. $400,000 list price would be $20k down pmt and you could have your closing costs covered using seller concessions.

Talk to a loan officer first to see if you can get approved for a loan of $450K.
