I would guess it probably goes up $50-$75 an hour for more labor, but they handled disposal and cleanup too so definitely worth it IMO.

Not a scam or pyramid scheme in the way you are thinking, but probably not the best use of disposable income for the frugal investor looking to optimize their ROI.Some probably need the forced savings aspect. 

Right now there are some pretty key elements that could greatly increase the power of that legacy depending on how your family decide to dispose of that property.1.

Our local wholesaler is a one email solution...I request current availability of a size, type, color and general model to replace an existing unit from the person assigned our account, they send me the detailed specs and cost which includes delivery, remove and dispose of old unit, and any accessories needed such as range pigtail, 3 or 4 prong, or washer hoses, etc.

The key is keeping it pumped and operating efficiently (educating tenants and no garbage disposals, etc.).

Great question, but it's not a question that I can answer for you...it just depends on what you're willing to sacrifice, what your goals are, what resources you have at your disposal, etc., etc.Obviously, NYC real estate is its own beast, and what works in many other markets isn't feasible in NYC. ...NYC is a notoriously difficult market to operate in, particularly for a beginner (and even for a pro)...I have quite a bit of real estate investing experience, but I'd be pretty intimidated to try to break into the NYC market (that doesn't mean it's impossible, just that it's probably a lot more challenging than many other markets).One thing I've found is that success in real estate investing often requires sacrifices (especially when you're starting out).

We do have physician loans at our disposal though with some lenders allowing duplex purchases.

The more ideas I have at my disposal the more effective I am at crafting agreements with investors.

There are a lot of moving parts - acquiring the asset, collecting on it, disposing of it etc, all of which have their own challenges.

Four lines, and a total of 30 amps per unit means that luxuries like a garbage disposer and a dish washer are likely to cause more trouble than they are worth.
