I contacted that agency this week online & got a response they are not writing commercial properties now. 

I’m always looking to implement best management practices so what can I, as a landlord, do to protect myself when accepting online payments?

That's what I've heard from others and read online as well.

@Yosef Ajami, we use Quickbooks Online for all of our Clients (including syndicators).

Every contact I needed for insurance, mortgage and cleaners were done online, mostly through connections from BP. 

Though I appreciate the idea of finding online resources and studying them, I find that a curated, tried and true formula (if it works) is much more worth my time than spending time trying to find which resource works best and then spitballing the ideas until something sticks. 

I wouldn't say you're going to learn as much going through an online course as you would an in-person one, but it is a lot more convenient. 

So here is what I do:1 - Get buyer criteria for what they are looking for (exact criteria)2 - Go source that criteria using data provider3 - Scrub the list and plan a marketing campaign around it (i.e) > Direct Mail > Cold Call > SMS > Online Ads > Social Media, etc4 - Once I get inbound leads coming in.

I came across conflicting information online, so I wanted to double-check with the knowledgeable folks on this forum. 

I have corporate bookkeeping experience and can see all the money coming in online but there is no one there I can speak with about our account.
