The ones with two kids supposedly saving up seven or eight years for their dream destination marriage in some tropical paradise.

(Which saved the property when the house next door caught on fire).

This comes with it's pros and cons but I don't see that as a bad option. or...I was also thinking of staying with my parents another year or 2, stock piling cash from the house flipping I do with my parents business, and then save up enough to buy a 8+ unit building to rent out.

I would also evaluate your budget, to save and try to generate more income.

There, you've been saved $40k lol

I’m going to sell this property soon as my HOA won’t allow me to transfer it over to an LLC.We want to purchase 5-15 doors (2-6 multi family homes) in the next twelve months and I currently have about $5000 saved and potentially have access to an additional $150k in family/friends money.

They're likely hoping you won't file eviction so they can save up enough of the money they are not paying you to find another place. 

The problem is that our credit scores and savings are low.

If I could save up $5000 by graduation do you think it’d be smart/possible for me to get a loan on a house?

Nobody replaces a functioning AC just because they've saved up.
