I have found the sweet spot to be $150K-200K. 

Welcome to BP - you've come to the right place for resources on real estate investing!

If you represent yourself, you have an amateur that is emotionally tied to the deal.

The answer will depend on many factors since it is a commission-based business.

I understand the cost of having to separate meters and purchasing additional water heaters and such will be hefty.

I managed it with spreadsheets and notepad on my phone only and used no accounting software the most part.Would you guys find more use in a service that replaces hands quickly or just having an app on your phone and computer to manage your flip projects that's visually appealing and easy to scale with?

The plan was to fix up that house an rent it out long term but with the market being high and I was moving out of the area it made more sense to sell at time. 

Would that affect the loan of our current property in MD? 

You may have to sell the whole property to access the funds in the IRA or 401k when you retire and for required minimum distributions. 

I purchased the house for 575k with the VA loan @2.5% interest rate.
