The complexities of selling investment owned property that has not seasoned yet are that many lenders will not underwrite them. To date it is not necessarly a FNMA guideline that a property be seasoned for 90 days before an offer can be WRITTEN, but many lenders overlay their own standards and this is one of them.
You can go through some lenders such as SDCCU and perhaps even BofA to see if they will offer you conventional financing for the purchase. If they do not I have a few contacts who we have used to sell our properties that we bought at trustee sale because the buyers own agents couldn’t figure out how to get this done.
Your agent, or shall I say it sounds as if you are working with the listing agent directly should have been able to help you with this.
