Have him tell you exactly how much money it will cost to finish.

Hello...I'm a beginner Real Estate Investor...I don't have all the answers but I did just the other day watch a video with Brandon that is finishing up this type of deal...actually he was recording the video at Starbucks...if i remember it correctly it was title...Investing in Multiple Family Homes...hope that can help u once you find the video...it is with Bigger Pockets...

I finished my classes in just three weeks, and passed my exam just a few days later, so I know there is a lot to learn to even get myself out there, and I am ready to hit the ground running. 

If your son has finished his degree recently, he can be eligible with short working history.

But this also gives you time to finish the repairs and get a tenant in there to start paying your mortgage.  

Running comps this way doesn't take into account updated kitchen and bathrooms, finishes such as hardwood floors/granite counter tops/stainless steel appliances or amenities such as pools and fireplaces, etc.The best way to get a comp is to look at what recently sold within a 1-2 mile radius of the property you're looking at.  

I want to vet an idea:I just finished my first re-hab on a BRRR property and the refinance is not going to get me enough money to do another deal.

I am currently looking at deals in the 21229 area surrounding The Catonsville border line/Cooks line area.

Arthur Cook thanks.l, I'm new to Louisiana but am aware of the heat in Texas.

You would need to contract it out to make sure it is finished in time and you will probably lose the majority of your equity build.
