I have made some great friendships and contacts through Bigger Pockets and the best part is that the cost is so minimal compared to the myriad of get rich quick internet guru packages, one can't go wrong here. 

You sure think you’re a flipper, are you asking the IRS to prove you wrong?

That’s just wrong.

The first time something goes wrong (and something will eventually go wrong) this negative cash flow will have you question the why.I have a fair amount of units.  

What you’re really paying for is saving time, tenant communication, and rent collection, not necessarily the cheapest repair quotes.If you already have a decent contractors or systems in place, there’s nothing wrong with using them.

If it's only rent collection, it's hard to go wrong with any choice.Here is a list you can check out for more options.https://www.biggerpockets.com/rei/pay-rent-online-payment-tools/

This should all be requested in the purchase contract for delivery by closing.Nothing wrong with buying tenant-occupied buildings, apartment buyers do it all the time.

@Kenneth Ye your math is wrong.

Someone managing mostly Class A apartments might not be the right fit for small multifamily or single-family homes.Communication Style: Pay attention to how quickly they respond and how transparent they are — that’s usually how they’ll treat you and your tenants too.Problem-Solving Attitude: Things will go wrong — maintenance delays, difficult tenants, late payments — so look for someone who’s calm, proactive, and solution-oriented, not just a messenger.Technology & Systems: Make sure they use good software for payments, maintenance tracking, and communication.
