Rentrange uses data from large property management companies just like mine.

This is where your focus should be, not buying section 8 rentals or focusing solely on increasing your portfolio by 2x, 3x etc.

One challenge to manage is being able to clarify for lenders on those rentals (if you have them) which amount of the premium should be paid for each rental so that they do not include the entire premium into their escrow analysis, inflating your monthly payment on that rental. 

I've got one rental property and would like to add to my portfolio.

Just needed for some tips on saving and managing money better .  

If they did, that’s really bad practice management.

There are certain brokerages that act more like true w2 employers, but for the most part you will be managing yourself.

@Brice Alef-Torrisi putting each property in its own LLC is usually overkill.Getting a bank account for each LLC is typically something you need to do to avoid "piercing of the LLC corporate veil" (actually depends on tax selection you made for LLC), but is also overkill.You haven't indicated how you are holding the deed for the latest property.If in your name or same LLC, you don't need a separate bank account.If in separate LLC, you can create a Master LLC, have each property LLC hire the Master LLC to manage their affairs, and just get a bank account for Master LLC.This is an opinion, not advice, so lookup CPA Frank Alcini in Troy for expert advice.

You can hear real-world examples of how others have built their investment portfolio and (hopefully) learn to avoid their mistakes.4.

I'm a local real estate broker, investor, and manager (100+ rentals, mostly Airbnb/STR and multifamily).House hacking is a tried-and-true method and in Sacramento you can produce some meaningful income while enjoying the appreciation and tax benefits of owning real estate.
