SOME, certainly not all, but some of the companies and individuals that I know who would be classified as gurus in this thread are doing nothing more than the same that the gym trainer, nutrition and financial advisers are doing.

The classification gets tougher out in the rural areas because an A class home can be a mile from a C class with no homes in between, so who knows what to classify the area, but my overall experience has been similar.  

Use a scale if you like of A to D, although it can certainly mean very different things to very different people, so some reason as to why you classify with.  

If you are looking within the city limits in particular, you cannot classify neighborhoods, as many have good pockets and bad pockets.  

These people can be your end buyer, or help you find an end buyer, likely with a small fee.The second I've done is to set up a landing page that I advertise through Craigslist and other online classifieds.  

Anyone doing classified ads?

there are  even some conventional loans that  might allow this ......if they don't want to be on the loan at all , you will likely need to  use  options that  classify the purchase as an investment property purchase  with you being the  borrower  ( assuming you already own a home ) ..thanks

For smaller multis maybe try online classifieds as well as some for sale by owner websites.

Find wholesalers in your area, it's really not hard, go on craigslist or check your local newspaper in the classifieds, you will see WE WANT TO BUY YOUR HOUSE. 

I'm not going to classify it as male/female but I am more comfortable having my team take care of getting multiple bids, telling the contractors when they don't do a good job, and dealing with late payments from tenants.
