Take AirBnB as an example: no one previously thought that a mass market existed for homeowners to let strangers in their homes, or for strangers to rent their space hotel-style.

I personally like multi-family properties as they have less capex (one roof to replace vs multiple) but that is just my style with investing.

We'll have two private beach clubs (most developments in Tulum have none) and amenities at least as good if not better amenities than any other development in town. the great thing is that being close to the beach fits my lifestyle and vacation style so my goals are congruent.

Be focused more on systems; i.e, are we saving enough money to invest by not indulging in other areas and prioritizing the right specific things, is the cost of this pursuit worth what you're sacrificing, if we keep $X set aside everything else above $X should be invested here in the short-term and this in the long-term.

The “first-come, first-serve” urgency might be their style, but without a timely responses, it could signal future communication issues down the road and frustration on your end.

But that really isn’t my learning style.

I know Dan Deppen and Chris Seveney both have membership style organizations.  

Should match many different styles. 

If you are willing to sacrifice part of your life style, you can always consider living one room/unit of the house and rent out the other vacant unit out to lower your monthly mortgage payments!

I'd bet that nobody with a single working brain cell will sign a lease with your brand new LLC without you personally guaranteeing it as well.As for the writing style, this is totally subjective and unique to each person, but I think you can be professional without being overly formal.
