@Greg Soon I work in QuickBooks online with only Real Estate Investors. :) 

we do a brief pre-application online before offering to physically show any apartments. 

I had another person try to bargain me down to $1700/month, and said she was moving out of her dad's house and so needed room to store boxes in the extra bedrooms. 

Also, access to online HMLs is compressing the total returns as the market gets more efficient.

However, I see how one may struggle to change the email, since it may have important information stored or they've reached full capacity for making new emails. 

A neighbor finds out he is living there with a simple online search and burns your house down3 A neighbor tells the local news channel and they show your house on the nightly news 4 A neighbor find out you are the owner with a simple online search and they begin harassing you and your family where you live. 

I am a landlord, broker, investors, etc. and have section 8 tenants as well - luckily I have a good relationship with my tenants but man oh man... dealing with their case worker was almost like they were paying out of their own wallet for a rent increase when in reality HUD had updated rent guidelines.Do you not have an online portal or account that you can access the section 8 landlord portal via?

Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.

You can find a map online to confirm if you wish. 

I’ve come across options like the Institute of Real Estate Management (IREM), National Association of Residential Property Managers (NARPM), and Certified Property Manager (CPM) programs, but I’d love to hear opinions on which have been the most valuable in practice.Additionally, any recommendations for resources, books, tools, or online communities that have been helpful for day-to-day management would be appreciated!
