@Daniel Moctezuma Sounds like you were wholesaling, which in many states is considered to be practicing real estate without a license - an illegal activity. 

I am looking actively myself right now.

They have a Google Group that is VERY active and you will learn a ton just by talking to the other NARPM members.

@Christian Mano,Here are the places I look:Loopnet and Crexi for commercialMLS (I have access) Open listing sites  (Zillow, realtor.com, etc.)Inventory list from brokers.Many companies and brokers will let you view their active inventory on their website or offline.

So on these, for a duplex bring in $1500 month cost 150K etc..In our market, that also happens to almost mirror what sold comps are, and also mirrors what the 'tax assessed value' which in my state is supposed to be the 'fair market value'.

Finally decided it was time to get started, and become more active while starting my real estate investing journey.

I know that may not be the answer you’re looking for but the only way to truly delve into the numbers and get a fair honest assessment of each property (we all know they’re different) is to take the time to get into the numbers on your own. 

When calculating the cost basis of a home, is it permissible to use the allocation of building to land from the county property tax assessment instead of an appraisal?  

@Josh July I'd say it depends on whether you want to be active or passive investor, and whether you want to deal with tenants or not.

Then, when you find a buyer, you are assigning your rights in your personal contract to that buyer in exchange for a fee.First, if you were working for me as a real estate agent where I was your managing broker, I have an obligation from the state to supervise your real estate activities and if I don't do that properly I can be reprimanded and/or fined and/or possibly lose my license.
