Should I refinance the property to a fixed rate and apply again even though I will no longer enjoy my low interest rate?

We had to redo all the plumbing, add a ton of electrical, fix lots of drywall, convert one room from a large recreation room to a bedroom, bathroom, closet, and laundry room, completely redo another bathroom, replace windows and exterior doors, add a kitchen where there wasn't one, paint entire house and flooring. 

I just completed the inspection yesterday and it seems the roof will need to be fixed(over 20 years, the boiler system is very old(there are 3 boilers), one of the 3 hot water heaters(HWH) is leaking and the 3 car garage (which is one of the main reasons the property is compelling as an investment purchase) is not structurally sound and may need to be demolished.

My question to you guys is do you think i should try and find a hard money lender for a fix and flip to start and can anyone recommend any, ill be relocating to the Dallas area soon so it will be somewhere in that area

If you are looking to simply fix and flip it, then appraised value is more important.

The $20k figure includes the financing to buy it then to sell it again including capital gains taxes and fixing a couple small things that led to be fixed.

I already had a background in fixing up places, but I really didn't start diving deep into renovation until after we had the first property.I know it's terrifying.

I've spent most of my adult life fixing things and its what I enjoy doing and want to help someone else out in their real estate journey as well!  

Some specialize in quick fix and flips.
