These can be "conforming loans" like FHA/VA for low down payment.If you don't live in it then it's similar but it's considered a commercial loan and you will likely have to come up with more down payment. 20%-25%

Loan (~125k @ 6% with a balloon payment at 10 years).  

If you are doing a BRRRR and you cannot afford the payment without the refinance at the end then you need to build up a deeper savings, higher income, or look at less expensive property.

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).
