This usually allows me to both earn the rewards points and leverage a small discount at the store. 

Health care alone for a married couple even on Medicare is going to eat up probably close to 1k. at todays numbers.. remember Medicare prices for how much you earn and if we are high earners it cost more. 

As a first time investor I think I’m going to let this one go by, as I’d really like to start my career on a positive note rather than feel like I am in over my head.

I'm about to be intentionally unemployed to pursue a career in real-estate investing. 

That said, those taxes are generally going to be paid on your earned income, which is the type of income needed to make Solo 401k contributions.

I am considering two options here: 1) Pay off the loans in full now. 2) Allow my money to continue earning interest in my high yield savings account until the moratorium ends, then pay them off in full.I have the following concern about waiting to pay: I expect my credit score will take a hit after I pay off the loans.

Trust me here; I started my real estate investing career buying $30,000 houses.  

I cannot give you advice on which route to go as I do not know your intentions for your career or real estate.

@Michael Haynes - issue is we’d be profiting $800k and I can only exclude $250k… Zero chance I’m paying that much capital gains tax for something I earned quite literally with my bare hands.I just got off the phone with 1031 intermediary and we might not be able to 1031 at all.  

Of course, if you owe no taxes because you invested funds from a self-directed IRA or don't earn enough to pay taxes, or the property will be sold within a year or two, a cost seg study is not going to be of value to you.
