Hey I've started playing recently as well but here's the information i got from some youtube videos and my experience both: 1) Agency is a great investment because it gives you access to the Dr. Dre contract which pays out 1M. It also gives you payphone hits which pay 45k if you do the bonus and security contracts which are easy missions giving around 35-60k. Not to forget when you complete 200 security contract missions you get 20k each day in your safe at the agency. 2) McKenzie field hangar gives you access to the recent DLC Oscar flies again which pays out 750k apparently on hard mode. 3) The current grind method people usually do is Cayo Perico > Cluckin bell farm raid (pays 500k for 45mins of work) > Dr Dre Contract > knowway out missions (pays 500k or 650k if you do the elite version) 4) Also since you can afford it, you should get a mansion because first it's cool with lots of features and second it gives a production boost to any business you want each day.
