Bubba, are you asking about purchasing an investment property?
For example if the purchase price was $60,000 and the property appraised for $100,000 would there be a way you could not bring money to the table since the house is appraised for so much more?
If so the lenders use the purchase price on a purchase loan. They do not use the appraised value. The only time the do is if you are doing home construction or home rehabilitation loans.
Regardless, you will need a down payment for a minimum of 5% or most commonly 10%.
Bourbonduke, I have not heard of a lender doing 100% investment financing for quite some time. Are you a Broker or a Banker? How long have you been in the business so far?
If you do a refinance there is no seasoning on Conforming Loans. You could use full appraised value and refinance. But, some lenders impose a policy on investment properties and require you to use the acquisition cost plus documented improvements as Bourbonduke says. This is not true in all cases.. I know several who will use appraised value and do rate and term. Then a few select lenders will allow cash out. Then even taking that a step further they will do cash out with stated income.(I only know of 1 right now though)
