If one home has a better site, view, proximity to ammenities or is nearer to the gate can all affect the value of the property to its benefit or detriment. The ease at which a sale may happen will be determined by one Buyer who is willing to pay more for what ever ammenities of which you speak and you have determined that should command a higher price.
You could argue that a SFH has the advantage of not having an HOA and its inherent restrictions on usage, parking, noise and payment for the amenities all of which are part of fractional ownership agreements. But some SFH are subject to payments for recreational districts, street lighting, and maintenence of green belt areas. So the division is not so clear in some cases.
I don't think the investment potential will be significantly different in either case. Only a ready and willing Buyer will determine which form of ownership is of more value and it will be determined by their own personal tastes.
In Some areas SFR may increase more but that only depends on many other factors. Condo's do appreciate also so you would need to sit down with an expert on this to get a better idea.
