Rehab Over-budget - Suggestions? (Saint Paul, MN)

[Aaron Rouser]

My wife and I purchased our first SF residence - 2Bd/1BA - at the end of July in Saint Paul, MN. The goal for this property is to add additional 500sqft of living space in an unfinished basement and add an additional bathroom on the first floor. After we make our additions, we move out, rent out the property, and then get started on our first multi-family property next.  

We originally set aside $30K for this project -- we came across these funds through saving for a year and taking out a loan against our vehicle. We've burned through about $24K on bringing aspects of the home up to code, framing out the basement, materials, costly mistakes, and we haven't even started in on the bathroom yet. We are certainly over-budget and are starting to think we bit off way more than we can chew for our first investment property!

For investors who have been in a situation somewhere like this before, I have two questions for you:

1. How did you end up pulling additional financing together in order to successfully complete your project?
2. For those of you who went on to buy another property, how did you get the funds together to close another deal immediately following your rehab on a previous project? (Getting started on a MF is very important to us and we want to start building momentum as soon as we can)

Thank you so much for your time, I'm open to any and all tips and suggestions!
