Biggerpockets has a Landlord package available for sale.

The price she quoted then went as high as 14K, depending on what 'package' I purchased. 

You only get all the bonus items with a paperback or Ultimate package purchase, though.

I have just received accepted HUD contract packages for 2 properties each with a different asset manager.

I've only begun studying up on real estate investing, so I can't help you a whole lot with the total package of investing in that area.

I get a real street address and they will sign for packages from FedEx or UPS. 

Depending on how the investment performs, that structure could be way worse for the investor than the higher sponsor split with a 1% asset management fee based on gross income.If you want to know how your $100K investment will perform, look at the package that the sponsor gave you.

This offered a mix of residential and commercial space in one package.

Every speaker was good; however, at the end, they're trying to sell $1,000 packages.  

I prefer to build or buy in bulk then subdivided into single units to resell for a 5-10% premium more than selling its a package.
