I saw an example recently in Bloomberg about how local regulations can really shape a landlord’s experience, from what I’ve heard.

You probably have good relationships locally so I would first think maybe upgrading to more units (if you like landlording and management) by selling the duds and then consider what you want to get into.

It’s a great way to meet local demand while creating steady cash flow.

If you're not having any luck with mortgage brokers (I'd search out the ones who specialize in investments), then go to your local REI meeting. 

Quote from @Michael Challenger: I would connect with local people at meetups, that might give you some contacts for private money.

Quote from @Fernando NA: Hello everyone,I’m considering purchasing a piece of land near Divide, CO, to build a small off-grid log cabin and list it on Airbnb or similar platforms.For those of you who live in the area or have experience with this, I have a few questions:>Is it possible to list such a property on Airbnb given the local regulations?

I'd start with attending local investor meet ups.

Please do this first:  contact the local Housing Authority office in your market area and obtain the landlord package.

That said, be sure to check your local jurisdiction for other regulations.

I believe that you don't get returns (failed to deliver) with bulk mailers so you don't know which addresses are bad.That's the simple stuff.My advice is to do various mailings that you or some prepares locally, that go out immediately, using 1st class postage.
