Do you recommend switching at around 30 properties or so? 

I have two books to recommend, one podcast, and then one more summit happening in person in May for syndication investors.

I would recommend buying a standard SFH with opportunities for an ADU, or a split floor plan where you could rent out the rooms!

I wouldn't focus singularly on individual city initiatives/projects and would recommend focusing more on fundamentals.

Nothing illegal about doing that, but if caught, the lender may call the loan due and if you don't correct the situation or pay the loan off, they willstart mortgage foreclosure.3) You could also go the HELOC route to tap the equity in the home, but the 12-month owner-occupancy will also apply AND the interest rate on the HELOC will fluctuate with the Fed Fund Rate.4) You could do a cashout refi as an investment property, but that will be at an interest rate 0.5-1% higher than owner-occupied rate.Suggest you meet with 2-3 lenders to explore your options about the above.Once you have access to funds, recommend you buy a 2-4 unit with 20-25% down. - You can buy owner-occupied, live in one unit, and fix up and rent the other unit(s).- If you're handy, recommend buying a property in the worst condition you can tolerate.

I don't recommend throwing the baby out with the bath water, and definitely make sure you understand the nature of the Mentor you choose.BP is a great resource to meet some amazing people. 

Any recommendations?

I'd like to be able to give a variety of options for the listeners along your recommendations and feedback on the options.

Any recommendations for starting strong would be appreciated.
