Trying to figure out financing option that makes the most sense

[Mo Abour]

Hello so here's what I'm (a general contractor) working with:The Deal:

• $20,001 for the purchase of
  • City of 100,000+ residents / majority low income but plenty of opportunity including financing the construction from the government
  • 9 parcels of land
    • ARV (As is): 63k
    • ARV (with improvement based on comps): $700k - 1.4MM
  • 1 commercial warehouse - 7000 sqft, undisturbed since it went vacant
    • ARV: $50k
  • 1 SFH- 5br/2ba - 20k sqft lot
  • 1 duplex- 5br/3ba
    • estimated construction - $30k

The business:

• 1 year old
• $200k revenue - $33k profit
• Established trade credit but vendors never reported
• Experian grade - B
• No debt
• $6k in outstanding invoices

Personal:

• Less than stellar credit
• Track record of successful ROI for partners and private lenders (family)
• Have a credit partner who will be completely silent

Credit Partner:

• 794 credit score
• currently has 11k credit limit
• 0% utilization

So in order to do this my plan is to:

• Increase credit partners credit limits
• Add me on as an authorized user to help raise personal credit
• Either do a business line of credit, hard money, non-recourse? or something else??? - then BRRRR

What do you guys think? Is there a better strategy than i stated above or would you change the product?
Would love your opinions as I have a few days left to close on this or walk away. Thank you!
