Rentals is the slower path, but gives you continuous cash flow, and your yearly profits are more more easily written off by having yearly expenses and yearly depreciation to help offset.It may take one of my rentals 4 years to deliver the same profits as your flip, but in year 5 and further I continue to earn income off the rental while you would have to keep exerting a (relatively) higher level of effort to continue to earn more income flipping.If flips is your favorite game, by all means you should keep doing it.  

Keep in mind any time you invest in this activity is time you could be investing in other active projects or endeavors to deliver accretive capital.  

Im trying to do that myself but asking the seller to deliver a unit vacant.

@Tyler PuzioIf you would want to live in this particular house, you can ask the Seller to deliver one of the units vacant at closing.

He has seen appliances advertised as having a small dent on the side, but delivered with a huge dent on the front, or other issues.

Recently, because I do not enjoy my job (delivering mail in Florida heat with no AC in a mail truck hotter than an oven) I started looking into real estate again. 

A co. named American Water Resources sent me a sales letter about buying insurance against water line failure of the line delivering water to my house.

And I don't think granite countertops or stainless steel appliances are any better at delivering those goals.

.- There was a fresh new paint smell when I toured the property.- There was some standing water that existed in the crawl space.- The property inspector was suspicious of water entry in the basement but had no proof as the area had been freshly repainted.My fear is with this property that the finished basement has a water entry issue.

Could use some fresh paint, etc.Would I get more value-add out of increasing exterior curb appeal, or adding a master bath?
