The lender could demand full payment (i.e. the entire mortgage) be satisfied within 30 days if you do a quitclaim to an LLC.

FHA 203k loans also lend you money to rehab as well for a similar down payment.

That requires a down payment (with us) of 3%-10% of the Purchase Price.  

Oops I posted the wrong thing but no worries, My true question is I'm looking to buy some multi-unit properties, and I don't have enough down payment yet.But I'm willing to work with other investors and build a team of other investors.Or should I borrow the money from a hard money lender for the down payment? 

Then you can open self directed IRA / 401K to invest but that will require more down payment and different tax rule.

What are my tax consequences in liquidating my IRA accounts for a down payment?

But you will have other expenses too: insurance, property taxes, maybe some of the utilities or HOA fees (I am assuming you are paying cash - if not, then a mortgage payment may eat up a lot of your profit).

Do you have down payments necessary? 

I would prefer to save the money and leverage debt to make another purchase with as small of a down payment as I can. 

This way I will have a large chunk of semi-liquid cash to pull out for either a down payment or for rehab in 1-2 years.2.
