What is your time worth to you?

You don't provide enough data to know.Every product is only worth what you are willing to pay for it. 

My wife and I spent 3 days prior narrowing down the list of properties to parcels that were worth bidding on.  

While they generated some cash flow, I found the effort required to manage them wasn’t worth the return.

This https://thestrive.co/pace-morby-net-worth/ jumps into trying to sort out his actual income and net worth but even then, it's a big question mark. 

I also like the sponsor, generally speaking, who is going all in with at least a third, and preferably half, of their net worth on the deal or fund.

You'll have to make some sacrifices, put in some work but I promise that its all worth it in the end. 

Before jumping into the condo, I’d take a closer look at whether the $300/month cash flow is worth it compared to other options, like a small multi-family property or a property in a higher-yield market.

Depending on your risk tolerance and investment goals, exploring short-term Treasury Bonds, high-yield savings accounts, or diversified alternative assets like private lending or REITs could also be worth considering.

In some cases interest paid on the HELOC can be tax deductible if the funds are used for home improvements.Best of luck from Fort Worth!
