It can seem daunting to get started, but you're in the right place. I would go through BP and find the "Getting Started" guides, the "Starting Out" forums, and travel through those posts. There is a lot of excellent information there, for what I think is a big question in a single post. Hope this structure helps:
1. Understand Investment Type and Strategy, pick 1-2 that work best for you. Most people start with Single Families or Small Multi Families (2-3 units).
2. Learn how to evaluate that type of investment type + strategy. Download a template here on BP, use a free tool or try to do it yourself. A spreadsheet is all you need, no need to pay for anything.
3. Find homes in the region you're interested in and start plugging in numbers. When I first started out I think I evaluated 100s of properties as I was searching and eventually you'll be able to tell a great investment without much effort.

1. The first thing you have to understand with is what type of investment (Single Family SF, MultiFamily MF, Short Term Rental STR, etc...) and strategy (BRRRR, Long term hold, Fix-and-Flip, Cash out Refi etc...) fits your financial goals and personal risk level.
2. From there, figure out how to evaluate those investment+strategies. Ex: How do I evaluate a single family BRRRR in the southeastern MA / RI area? I would find a template on BP (an excel document or tool that evaluates a SF home), there are very smart and experienced people here to lean on for these things. However I found trying to create it yourself is the best way to learn. Finding/re-using or DIY are the ways to go, there's no need to purchase any evaluation tool.
3. The last step is to start using the tool, pick some random houses or houses you find interesting and start looking at numbers. Based on your strategy you might want to connect with people here to figure out how much things cost, or what's a great up and coming region. Other folks start with picking a region (like Providence, RI) and analyzing properties there, I do the opposite, neither way is better.
