Wyatt,
I would echo many of the points made by the others. You need to build your team for your real estate investing business. You need a quality realtor that can advise you on current value and after repair value estimates. You need an insurance agent, a real estate attorney, an asset protection attorney, and varies contractors for starters. Lean on your team to make decisions, but know in the end it is you who has to make the decisions.
Make sure you learn your market well. Track what properties are selling, with what features, how fast, and for how much. Also track what properties are renting for and what areas are in demand. Make sure you calculate the estimated rehab cost, and hold time. Only make repairs that make financial sense. I usually add something to a property that the buyer would not expect at the price point. For example, I often put in quartz countertops in the kitchen when properties at a similar price point do not have them. I find by doing so my properties move quicker.
There is nothing wrong with doing most of the rehab yourself, I did a lot of them in the beginning, but know you will likely make more in the long run if you hire out the work. I learned a long time ago that I should spend my time finding and negotiating the deals not rehabbing the properties. In the end there are many ways to make money in real estate you just have to figure out what works for you as well as what you enjoy. Good luck.
