The down side of using New western is that once you sign the contract and give them the earnest check you have no due diligence period and because the market is so hot now if you postpone signing the contract until you do your due diligence the property is gone, most properties don't last a full day, for that reason I think they are more suited to full time experienced rehabbers.

If you have these hot deals find a hot money partner and get at it.. this is one of the biggest failures I see in those starting out.. they don't want to share can't put the deal together and just miss out totally half of something is better than 100% of nothing and or taking forever to get going.
