Alternately you can get a floor AC that you can roll around but if it stays cool maybe you don't even need it. 

I can borrow 10k through a 401k loan @3.75% payable back over 5 years or use money that I have in an IRA and roll it into a self directed IRA?

I'll just have to battle through the beginning stages, and rely on the income from my current employment to get me rolling.

I need a larger bank roll to flip more houses at a time.  

I have a 403b and a pension fund payout that I will be able to roll over into something (what?).

Unless you want to roll the dice, I would definitely recommend title insurance.

@Jasmine ZA suggestion you may or may not of heard about is being a private lender to rehabbers earning 10 to 12% for short-term loans, receiving a mortgage or trust deed security for the loan and rolling that over and over.I would take that interest money and paid down student loan debt.You need to get your debt to earnings  DTI downYou could also buy houses on land contract in Wisconsin then doing a lease to own exit, land contracts are common in Wisconsin

Account Closed This project was financed by a "mini construction loan" where my rehab costs and price of the house were rolled into one loan with my local bank which I have extended for a fee of course.  

Some people get on a roll and feel invincible in a cycle like it will never end.

Can an SDIRA LLC be rolled over to a Solo 401K?
