.: REI nation is a reputed turnkey provider but they just sent me pictures of the property and asked me to choose.

No.I provide cable channels (I'm not cheap and have nice properties) and have smart TV's where they can log into any of their streaming services.

The turn key property is on a tiny island in the Chesapeake Bay in Maryland called Smith Island.

That makes the investing and property management a LOT easier.  

Some of the most in-demand upgrades include:✅ Modern, open-concept layouts – Knocking down walls to create larger living spaces✅ High-end but cost-effective finishes – Quartz countertops, LVP flooring, and neutral color palettes✅ Energy-efficient upgrades – Smart thermostats, updated HVAC systems, and LED lighting✅ Curb appeal improvements – Fresh exterior paint, desert-friendly landscaping, and modern front doorsFinal ThoughtsWhile finding a property that offers both appreciation and cash flow is tough, there are still solid BRRRR opportunities in Phoenix if you know where to look.

Similarly, if you put several Class D tenants in a Class A 4-plex, what do you think will happen to the property?

I would tap out and consolidate into better property(or properties) in other areas.

I did another one were I paid 240k for the property and a developer swallowed us up in 18 months and we sold for 970k.. without doing much to the project.As Cody mentions this is not for everyone and I would say very few could do this in reality. 

Unless you still want to buy the property, the seller is in breech for not closing because you are full ready to close but they haven't or refused to sign anything.In NC if the seller breaches, the buyer can sue for specific performance.

ACT when they go to sell, or takes the property under contract without telling the seller he is not the final buyer and then assigning the SubTo property to someone else for a fee.
