hey everyone, 

A bit about myself, im 22 studying computer science part time in college and i have about 35 credits left and their only major classes for a bachelors degree. I cant grip myself on the thought about  a 9-5  job and none of my family members have had a job ever. thats why for some reason i cant finish those last college courses. 

i have a seasonal business where i make good money but i want to start saving it, instead of just spending all of it on my car for upgrades.

so all my family members are in the construction industry which brings me to the conclusion that i should buy rehab and flip.

i have about 15k cash and when i sell my 370z il have about 35k to invest.

im looking into flipping in jersey where i could actually afford someting.

i looked into some properties obviously the easier it is to get into a property cause of its low cost of buying, the crappier the deal is. while the more expensive properties you have less competition.

my first question is after i saved up 50 k should i buy a house that is in that range for full cash or if there is a  great deal say on a 120k house should i pull out a loan  and when im done flipping i do the brrrr strategy.

i have excellent credit im just worried say i keep on flipping and my credit gets screwed over by so many inquires doing 4 -5  flips in a year.(just in case)

lets say i do a loan and they offer me that 20 year one, and i only need it for say couple of months until i flip the house to pay off the loan, am i paying them off with the principal plus 20 years worth of interest or only interest for the months that i used the loan.

Thank you
