I know there are a few videos on youtube worth watching about how to generate your own leads and with minimal amount of money you can use options such as direct mail, signs, a website where distressed owners can input their information and it will relay them to your email. but definitely worth looking into. 

Does anyone know a reliable and flexible portfolio lender in Phoenix, AZ that you can direct me to ? 

Someone with whom you've directly worked with or heard is a rockstar in the area.

Auction.com (https://www.auction.com/lp/learn-more/) gives information directly on their website.

With 3-plexes in Boston routinely selling close to $2M and in places like Cambridge, as high as $3M, these properties are simply not good prospects for most investors.The solution in eastern MA is to get away from the city.  20-30 miles out, properties are a LOT more affordable. 

Meaning we don't compete against each other directly, so there is no real market force that would make them act differently due to some competition environment. 

Then you can take action in a specific direction. 

I have done some direct mail, but it seems to be pretty ineffective to me, it is much easier building clients organically by networking with people in your real life, joining meet up groups, and just talking to everyone about what you are doing.

@James SyedI worked with the VP & Branch Manager of the Rock Hill location, and he directed me to the right people after that.

In this market, however, there’s not a lot out there so some people are using direct to seller marketing and are finding success that way.
