I sunk a large amount of capitol into these when I purchased them just to make sure they were nice. 

My plan is to set up a syndication fund with Canadian (and U.S) investors to purchase short-term rental properties in the Puerto Vallarta and Rivera Nayarit area (which is booming).

Before seasoning period ends, I want to sell to my younger brother who purchases with conventional mortgage.Is there anything wrong with this idea?  

They develop, they build, they finance, they property manage, they will have HAO, cleaning crew etc. etc. etc. so the subsidiary companies make money every step of the way.From investor perspective: The investor pay $15 K to reserve the right to purchase 25 multiplex over the year of next 5 years. 5 each year.

@Prashanth JagadeeshRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

They specifically specialize in group vacations, so kind of similar, and no doubt have spent a ton of money analyzing and figuring out what works. 

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.

Also, important to confirm they will be warrantable condos for end buyers otherwise it will be very difficult for end buyers to secure financing and thus purchase the units.

It is possible to get 90% of your purchase price and 100% rehab funded as a first timer in 1-4 units.
