Now that I'm on the sponsor side, I've been able to incorporate a lot of their financial reporting into our projects. 

I’m definitely going to incorporate that into how I do my investing.

As the HOA can require their policies be incorporated into Leases, which the Renter signs, and the Renter and owner could co-sign the pool access agreement to get the access card, this logic seems a little light.Anyone have experience with this restriction and have any ideas of ways the HOA can allow renters access while still acting to mitigate the financial/liability risk of allowing renters' guests and reservations that is somehow different from an owners' risk?

I will incorporate what you suggested into what I ask.

I also like to recommend Cohen and Dube's "Legal, Tax and Accounting Strategies for the Canadian Real Estate Investor" ... it is a good reference over all, but it is a decade old now and could use a refresh to incorporate regulatory changes. 

There are many reasons to incorporate in Delaware but a lower fee is probably not on the list. 

What strategy would you incorporate to start-up quickly?

Smart investors will figure out how to incorporate technology into their business while simultaneously maintaining the personal relationships that they have worked so hard to create.

Otherwise, consider incorporating lease options, subject to, wraps and a host of other creative financing techniques discussed throughout BP. 

I like to use them because they already have the legal information incorporated in them that are specific to your area.
