Are you a real estate investor out looking for a creative loan?
Hoping to find a lender who can work with quick "flip" transactions?

Congratulations with your future in real estate investing. Unfortunately, I am probably NOT your answer for a loan.

If this is your situation, I CANNOT help you:
You have found an under priced property that is worth $550,000 (after a little work it will be worth $700,000).

The seller has agreed to sell it to you for some lesser price like $400,000 or so. I would be the first to congratulate you on finding a great deal, but I would NOT be the lender you need to make it happen.

I would base my loan amount on the purchase price or appraisal value, whichever is LOWER. So, in this example I would make a loan based on the purchase price of $400,000, and 50% of this is a loan of $200,000.
My money just doesn't work on these type of investor flip properties - try someone else, and then call me when you actually find someone who will do this.
Note: If the property is free and clear or has a low existing debt structure, and/or the seller or existing lender will take a 2nd position lien behind my first position, it may work out.

Example:
Appraisal Value: $550,000
Purchase Price: $400,000
My loan amount: $200,000
Cash down payment: $20,000
Seller holds 2nd: $180,000
