@Moises Silva- if you purchase next one as a rental - getting traditional financing should be best route to take ..you will need min of  15% down 

@Nayeem Khan @Jason Bott - any ideas if these policies are more or less expensive than more traditional homeowners policies?

They also sold them on a mix of traditional sale and held notes on some.

Both can be powerful tools for investors, especially when you’re looking to maximize cash flow and returns.Since most lenders have a minimum loan requirement of $75K, you might want to explore hard money lenders.These lenders specialize in funding investment properties, even for amounts below traditional lending thresholds.

Those major cities that you mentioned are fantastic options and have TONS of potential tenants/students, but their barrier of entry is much higher than traditional "college towns" like Lubbock or College Station.

We have a buyer looking to do traditional financing for each individual home as a single family residence. 

For a cash-out refinance on a vacant lot, finding traditional lenders can be a bit tricky as most focus on developed properties.

I would use a property manager to manage them as I only have experience with traditional rental properties.I would love opinions from investors who actually use the Section 8 program and those who do not.What is your opinion on which one is better long term and brings in more cash flow now.I appreciate any information.

I'm wondering if others have gone this route and what their experience has been with doing things this way vs traditional booking sites? 

Given your presumed lack of real estate experience, OPM (other than 'traditional' bank financing) is likely off the table for now.
