I am Lean Six Sigma Yellow and Green Belt Certified, with experience in operations, process improvement, and procurement within the distribution industry.I am very motivated to learn, connect, and grow in this field.

A househack will teach you almost all of the fundamentals of REI; you'll learn how to analyze properties, how to build financial models, how to work with agents, tenant procurement, management and retention, vacancy mitigation, property maintenance, tax strategy, etc., etc.

I can understand if they are the procuring cause for a tenant or non-tenant buyer sale, but this seems a stretch.  

The 5 years is just the loan period you use with your investor to procure the $30k, assuming you use investor money. 

On the front lines of deals from procurement until exit. 

Here is one procurement spreadsheet I did in 2023 for a property we were buying in Georgia. 

I did the design, permitting, procuring materials, and I was also the GC. 

But regardless, one easy thing would be to take on purchasing and procuring finish material.

(There's a continuum, I get it - but hopefully the sentiment lands.)Of your "questions" at the end of your post, I think your first outcome (1.) is probably the most likely and I would begin preparing for that eventuality (i.e. engage a L/T attorney, procuring cash reserves for non-payment during eviction, funds for extensive renovation). 

Used bank financing he had procured when development started, so was money committed at lower rates.
