All you get is what you can export/import via CSV file:(We use Propertyware, have experience with Buildium and have played with Appfolio and RentManager.Buildium is for smaller companies.The other three are tied, the differences being how much automation & customization you want to do.If you don't see yourself growing beyond 150 units, go with Buildium.If you're not very techy and plan to grow over 150 units, we'd recommend Appfolio.If you're techy and plan to grow over 150 units, we'd recommend Propertyware or RentManager.Of course, schedule some demos, take GREAT notes and them make your decision.FYI - there are MANY new options on the market, RentRedi, TenantCloud, Apartments.com, Hemlane, Rentec.

(SpaceX)- Book Recommendation: The Millionaire Real Estate Investor.

Scott's book, hard money isn't always recommended and it's better to go with a portfolio investor such as smaller banks, or partnering with other investors, or of course seller financing. 

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

The attorney may spot issues and recommend an objection letter.

I highly recommend a PM, but some people have the time and ability to self manage their properties. 

Additionally, I recommend reaching out to @Kyle Mast for his perspective.

Anyone had any experiences/recommendations/advises in this regard?

I sent you a connection with a quick question regarding the lender recommendation.

I would suggest you go an interview a few lenders, they have many different programs that can help you here.I can share with you the ones I recommend in Dallas.
