Hello Ally, I highly reccomend working with an agent at Marcus & Millichap, they have excluive listings across all 50 states and canada in all commercial real estate product types: Multifamily, Self-Storage, Industrial, Triple Net Retail, Mobile Home Parks.

Do you physically meet them at all, ever?

Most if not all brokers will come in .25-.75% lower on comparable products.

Are there non-recourse loan products available?

Most lenders have two loan products which will be needed to accomplish the BRRRR method.

The successful wholesalers I know either (1) spend $75,000 or more annually on marketing or (2) wholesale as a by product of a fix n flip operation, like Homevestors.

@Joshua Gwaltney apply for fix and flip financing, which includes purchase and reno costs, then refi into a 30 yr product once the property is stabilized and owned for 6 months.

Short of physically visiting the property and talking to people, there's not much else you can do.

These guys are often more familiar with day to day product instead of high-end/spec homes, and good property management companies will cull a list of responsive, reliable, and affordable contractors that are licensed (if required) and insured.  

I think it's time for you to have a productive conversation with her about what you're looking for in feedback, turnaround time, as well as deliverables for the weekend.
