New investor, how does a evection lawyer work?

[Nicholas Wilson]

I’m looking into buying a rental property in the next couple months. I have been doing lots of research and have heard people saying to get an eviction lawyer. I was wondering should I contact one now before buying a place or wait until I buy a place? Also how do they charge? I have never worked with a lawyer in anyway so not sure how they get paid. Any help or suggestions would be appreciated. I have some friends that have rentals and they have never said to me about getting a eviction lawyer but if they are cheap enough for and can help me relax it is worth it. Thanks all
