@Michael Perry I (only) do "turnkey". My definition of turnkey is: no need to do any work for it to be put into service (when buying from a developer) or remain in service with an existing tenant in it (when buying from a non-developer). If there is work needed, it would be only cosmetic such as some interior paint here and there, maybe, maybe a new carpet, replace a ceiling fan or something like that. Minor stuff in the grand scheme of things.
Having said that: why would this not cashflow? As others have stated already, if you buy right (i.e. don't overleverage; I have voiced my opinion on this topic recently here on BP in a few posts) and the building is in good shape and tenants are ok with low vacancies then there is no reason for such a "turnkey" property to not cash flow.
I would even go ahead and say: why and how would a "non-turnkey" cash flow any better? Because if it's not turnkey then you need to put money in it which will give you an ARV which then will have to be put into relation to the rent (and the associated mortgage/costs).
With respect to @David Song's post and him saying that this is all a scam: don't agree. At least not when it comes to buying from either a developer or a private person/investor. While there might be people/institutions out there trying to sell you a property priced (way) over its value: yeah, so? If the buyer buys it then that his/her problem, not the seller's! Are people buying Louis Vuitton handbags because they are actually worth that money? No, they don't. They want the damn thing and are willing to pay what the seller is asking for. Their problem, not the seller's/manufacturer's. The market dictates the prices. Supply and demand.
As regards David's statement: "If the property is priced good enough with high cash flow, with enough appreciation potential, without all the trouble, why don't I just keep it. Why would I offer it to someone else?"
Because there is an immeasurable amount of situations and reasons why someone has or wants to sell. How does this make the sale a scam? It doesn't. What David is in essence saying is that every flipper is a scamer. I don't think that will bode so well with them. ;-)
So don't be frightened by all these "buzzwords". If you want to invest into real estate you need to find the right property. Whatever someone is calling it. If you do, it will cash flow. If you don't it might still cash flow and yet still be a bad deal. Heck, it might not cash flow initially but still be a good deal! Everything is possible.
Do be careful, or rather: prudent, when getting into this game but don't over-analyze things, especially not with a Townhome/Condo. And make sure you have enough equity in there initially. Leveraging is great, but it turns against you if things go south and you don't have enough other reserves. Good luck.
