If you are setting aside funds for capex, taxes, insurance, or other expenses that don't occur monthly, transfer those funds to Savings each month and hold them there until it's time to spend them.

I was looking into unsecured personal loans but they only cover about 50-100k for 1 year duration.  

NOT judging, I am truly curious the mindset's of such persons.

They knew all along they weren't going to fund this flip.

Buy a few things on credit that you would just usually pay cash for.I personally would not rush into a Heloc or such.

You can establish a personal LLC and use it to buy a business.

There are plenty of hard money lenders out there to fund your projects.

Is your $15k even enough of an emergency fund for you personally?  

Quote from @Jokari Trueheart: HI, almost 11 months ago I purchased 3 duplexes and I borrowed the funds from my personal residence which I took out a equity agreement for the down payment on the investment property, great idea at the time because I have 10 years to pay it off and theres no payment requirement, but , I learned more about the consequence that it takes a large chunk of my equity the longer I take to pay it back, so my goal was to refi cash out the investment property to pay it back but I don't think theres enough equity yet to pull the full $106k needed, I only borrowed $88k but with the equity percentage for one year i'm paying about $18k in equity on top of the amount I borrowed if I pay it off in year one, so I need this paid off ASAP before it increases more.

I don't know this person or company from a sack of salt or what  they do..
