This deal may work better as a Buy and Hold Rental using conventional financing to acquire the property.  

My question is would it be possible to get another HELOC, or home equity loan, etc. for an additional 30%-40% possibly?

I am in the middle of acquiring a lot zoned for duplex and it is only 3,700 sqft.

My short term goals in real estate are acquiring a buy & hold property near the Jacksonville, FL area.Looking forward to meeting and working with everyone!

Growing up, I helped my parents with their house flipping and rentals, so I've witnessed what REI can do, I just hate that it took so long for the light bulb to go off.Current State:I am looking forward to gaining as much understanding as books can give me, but mostly eager to acquire our first property and learn while doing.

Can you post any additional details about your deal? 

I'd say that after the job is completed, I might need to revisit the project to make additional minor repairs to the garage, and the money is intended also for electricity needed for the minor repairs, if they ever come up. 

(Sorry for the additional questions, but I know I would have these questions in my sleep.)

. (~15k) Additionally, sounds like you are living in it.

I'd need to charge $50-100 each time depending on location and can put that into a buyer's agreement as an additional charge to you at a future closing.
