One thing you might do is sell your more expensive properties and buy less expensive ones. 

I want to obtain more properties through other loan products but unsure where to start.

Does anyone have experience buying properties for cheap from land banks, renovating them, and renting them out/selling them?

Depending on the property far more than the acquisition price may be required and that will also dictate the best loan product. 

It is worth noting that this is a completely different product from Sean's.

I guess I could do some work-arounds -- maybe reserve one unit in the first purchase for use as an AirBnb, and reserve my own time in it when needed - instead of claiming it as a primary.Are either of you (or anyone) familiar with a finance product/loan that will allow me to purchase under $150,000 (w/ strong credit) and do much of my own work and live-in a portion as a primary residence?  

She's a beast and you'll likely get approved which will give you a revolving source of funds to keep growing Griffin what terms are you seeing on products like this? 

I know many investors go out of state for buy and hold properties to generate passive income, but is Blythe a lucrative market?

Quote from @Zachary Young: Hi all, I am looking into buying my first rental property.

This would allow you to sell a property you had purchased with the intent of holding for productive investment use.
