This does not even register as a 1 on the scale .

:)Having done something similar years ago, would advise you NOT to quit W-2 until you have a crew you can depend on to do at least 80% of the rehab work.You should also be building a network that exposes you to more deals than you can currently handle.Otherwise, you're just trading one job for another and won't be able to scale enough to generate the number of flips you need to replace W-2 job.

Plan is to buy SFH & Duplexes and start out small and scale quickly once we figure out the market.

Would love to connect and knowledge share about how I scaled my portfolio. 

If you look in sub markets of larger cities mostly around the South and Midwest it can be achieved more at scale. 

I'd saying following your experience and scaling off of your flips would make the most sense as you can use skills/knowledge you've already cultivated.

It is the easiest software to get help with as you scale, and the easiest to delegate to a professional. 

You need to make a ton of money at first to scale.

He may stop doing it as a courtesy, or you may need to explain that it's a requirement to keep working together and he needs your work so he stops taking other work, or he may say that he can't afford to pass up the other work and you can negotiate a better pay scale or a bonus for timely completion. 

Looking now to scale and network here in Florida.
