Anyone familiar with PMs who collude with house-hunting companys to purposefully make me more inclined to sell?

I took quite a break from buying properties and now on the hunt again.

In other words, I think we will probably have to be on the hunt for a very good deal or a very distressed property, and will not be investing in million-dollar multifamily properties... yet!

I'm on the hunt for real estate meetups to expand my experience and network, but I must not be looking in the right places.

There are a few options(1)You can get connected with the larger wholesaler firms in the area (2) go through PCPAO site and skiptrace the buyers of similar properties as yours, (3) hunt down the agents involved in the sale of properties similar to yours or go to local REI meetings and pitch it to the investors there. 

I recently got pre-approved and am also on the hunt for my first investment property.

Spent a summer weekend hunting for on-market deals on days off with a realtor.
