I have W-2 income and three investment properties.  

Maybe some sort of "white glove" organization exists, but doubtful.Also, it would be better to split it up for sourcing issues, just like hiring trades instead of general contractors.For example, it took me two years to find my agent. 

I got quotes from a variety of sources from $400-$600 per opening.

Every investor’s goals, resources, and strategy are different, and there is no one-size-fits all solution to market finding.You’ll walk out understanding:How to balance your goals for cash flow and appreciationWhy home prices don’t paint the whole picture for affordabilityHow metrics like the rent-to-income and rent-to-price ratios are similar (and how they aren’t!)

Should I agree to this so I can make some additional income, or is this opening a can of worms that I don't want to open? 

All the benefits of living near CA but no state income tax.

I haven't seen this lately but be careful and read the terms - there are often terms in the mortgage that preclude using the second home as an income property or limit the number of days you can be paid rent on it.

These type of loans have the least requirements and are usually approved based on the investment property alone and not the income of the borrower.The highest interest rates will be from a hard money lender.

The data the city requested was more than would be reflected on my income taxes. 

While I'm intrigued by the idea of DSCR financing and hard money lenders, I feel they might be a bit too pricey and risky for me at this point.That said, I'm excited about the prospect of partnering with someone on a deal, whether it's as a minority partner bringing value through sourcing deals or as an equal partner sharing the workload.If you're on the lookout for a young, motivated investor to collaborate with on future opportunities, I'd love to chat.
