Buy and hold investing

[Dante Campbell]

Hello everyone I’m back again with more questions and a little bit of an updated plan as I’ve been doing some research just want some feedback and possibly some motivation stories appreciate it ahead of time.

I'm 21 working like a mad man at my day job picking up as much overtime as possible and listening to podcasts all day while I'm there learning on the clock as well off the clock I make decent money (not enough to raise a family on) so my plan is to use the BRRR method & house hack a duplex - quad and buy and hold long term and eventually go commercial with big apartments so I can have all units in the same place i don't have a team at the moment nor have I contacted anyone as I don't have a need for them yet I'm still in my accumulation phase (knowledge and capitol)

My questions are

Is there an equivalent to a 203k loan that’s conventional I don’t want to have to deal with mortgage insurance forever?

If there is one would which would you prefer and why? (I’m looking at the 203k for a lower down payment and rehab help)

Do people refinance to get away from the pmi?

How does refinancing work? What does it do?

And last but not least for the moment I’m from the great city of Pittsburgh are there any meet ups and or groups that I could join thanks in advance
