What system besides excel can be used to keep track of the metrics on how the property is actually performing after purchase (long-term basis).Thanks in advance for the suggestions 

@Casey MurrayAshish and Natalie both provided an excellent idea regarding investing in the QOZ.I just wanted to touch base with you on some of the numbers in your post.Your clients may be subject to more than $140K in tax.They may also be subject to the 3.8% of Net Investment Income Tax.Furthermore, since you are in CA, I assume your client is also in CA, and they may be subject to California state income taxes.The seller may be able to offset it by using closing costs at closing to offset some of the gain.The more the reason to consider the QOZ.

Before I could afford BP Pro, I made my own spreadsheets in Microsoft Excel.

ALL in excellent shape .  

Start watching YouTube videos, read The Millionaire Real Estate Agent by Gary Keller, go to real estate meetups and ask real estate agents questions, etc.

It’s an excellent place to start, and can answer many of your questions.

And this is excellent information.

I joined Bigger Pockets yesterday after watching a ton of their videos on YouTube.

You have an excellent strategy.As long as your first intention is for that property to be your primary, you are in the clear.
