However, I kind of don't want to wait till retirement age to reap the fruits of my labor.

This is my one year anniversary of being on the site I am kind of a nut 3612 posts over 2000 votes ( so some people like what I say) and not one post was a welcome post I leave those to others...

I'm comfortable paying 8-10% above the cost to the wholesalers, but some are 25-50% and that's nuts! 

I have friends that won't take less than $300/door and 15% COC, because they're retiring and need to live off of that cash flow, and others that don't care much at all about cash flow because the amortization is setting them up for a long and fruitful future.I had a property that cash flowed at $100/year, but was gaining almost $15,000/year in debt pay-down -- I sold it to recapture that equity -- on paper, it would have looked like a dog if you were only looking for cash flow!

A vacation rental in Hawaii or a very high end home can run close to 50% but, as you would imagine, the level of service provided to the property is much higher.Without knowing more about your rental, location, season, and the services the PM is going to provide, I'm not sure you can out-of-hand dismiss them as nuts.

Many times the benefits are over blown by the privacy nuts.

As a result, the home prices have been nuts in the area but there are deals out here. 

The NUTS 

With that said there isn't much low hanging fruit, i.e.

So In Boise Idaho I can build SFH for $130 a foot but the land is nuts like $100k per house and I would make about 10%.
