Breaking down multifamilies more, you probably can make more money with less desirable properties that you have to invest money into, but that takes time, money, and a tolerance for risk... there's a lot of guides on this website for all the different types of real estate investing you can do. 

I stumbled across this website and figured, why not?

I was looking for an online software that I can access through website or mobile app.Originally posted by @Peter Sautter:I use LandlordMax for my ten units across two buildings. 

Any person, partnership, association, corporation, entity, or their regular employees, who as owner or lessor perform any of the acts enumerated in §§ 54.1-2100 and 54.1-2101 with reference to property owned or leased by them, where the acts are performed in the regular course of or incident to the management of the property and the investment therein."

Do you have a website or do you market on other channels?

I've started browsing on Zillow and websites like that, I'm reading books like "What every real estate investor needs to know about cashflow", and listening to the bigger pockets podcasts. 

@Eric Fernando You should start by looking at the county property appraiser website and check out the neighborhood and the zoning for that particular property.

Any suggestions or references would be greatly appreciated! 

I hear you about Appfolio--I have not signed up for the demo, I was turned off by their website that provides zero info (there is literally only one accessible page!) 

Check with your county's website.
