You'll get better pricing if you use the Hard Money lender to finance the rehab as well, however, the way it works is you must request a draw.

I have come across a wholesaler who is assigning a contract on a property where they have negotiated seller finance terms with the owner.

I advise my clients to get a PML that will finance 100% of the purchase and rehab expenses so when the property is stabilized, we can treat it as a rate and term refi and use the new improved value from day 1!

Like I said this will vary dependent on the lender, experience, credit score (not as important as traditional financing but can help).

Can they provide some seller financing? 

Side note, if you will be financing a condo that allows short term rentals, you will most likely need to obtain non-warrantable condo financing, not conventional.

I've found that have a small yard and allowing pets increases your application pool.

Know your applicable laws.

I sold it under owner financing for 2 years and then was just recently paid off.

Do you need help with financing?
