I do not plan on paying for the service that she signed up for but also not clearly sure how I can help.

Do you pay them? 

wife didn't tell husband for two years during covid she wasn't paying mortgage. 

To name a few she damaged her unit and the unit under her and not willing to pay for the damages that she caused (I had both places fixed).

I have partner 50/50 with new flippers, but they put half the money into acquiring the house and repairs, and I pay the other half but I use my crew to do the flip. the other person needs to have skin in the property otherwise, I just pay them a wholesaling fee.I recommend starting by using a hard money lender, as they will take risks when someone is new, and they won't lend you the money unless they feel confident the deal is good. so you are confident you can be successful.you may pay some hight interest rates, and points, but at least you know you may make money at the end 

Work my job, and pay down the current mortgage?

Despite these hurdles, the deal highlighted the importance of thorough market analysis, strategic planning, and strong partnerships.

Purchase price: $170,000 Cash invested: $150,000 Renovation and hold plan.

I understand that the Section 121 Exclusion for Primary Residence allows you to sell your Primary residence and not have to pay ANY capital gains taxes on the gains/proceeds - as long as you use those funds to purchase your next Primary residence.What I cannot seem to find the answer to is - what is the maximum timeline allowed from Sale of the first Primary to Purchase of the replacement Primary residence? 

I hope they offer atleast 10. 5 would be a huge risk because even though the plan is to cash out refinance 2-4 years post closing date and extend the loan… 5 adds a huge amount of stress.
