Sharaya: Upfront fees, bait & switch loan terms, and onerous loan-to-own documents are the areas where you need to watch yourself the most.
1. Frankly, a true "old school" HML shouldn't run a credit report. The strength of the asset and your equity in the deal is your credit. However, many of the newer "institutional" lenders are requiring minimum FICO scores (630) to fund a loan because it was a condition of their Regulation A+ capital-raising documents.
2. If they have a significant application fee, I'd be wary. This is simply another revenue stream, and not meant to defer their overhead cost.
3. After your application, make sure you get a firm loan proposal including rate, term, conditions, and estimated cost.
4. Most importantly, the lawyer closing the loan works for the lender not you, even though they gave you a bottle of water and have a bowl of mini-candy bars in their mahogany conference room. Have your attorney review the loan documents prior to closing.
5. If the loan terms change at the closing table--bolt.
Good luck,
Steve
