@Account Closed "Worth it" is subjective to each person's own goals, talents, time and tenacity. There are ways to get into real estate without much money, but the process is sped up if you do have some money.
Not sure if you have a "day job" and this is a supplement as you referenced convincing your husband and two friends. Perhaps one of you should pursue being a real estate broker, which would provide an avenue for revenue (commissions from transactions) and would also put you in a position to sell your own properties if the intention is to fix & flip, which would allow for controlled sales costs. It would could also provide a good education by learning the real estate brokerage business, which would assist in comping deals, having access to more data, and making connections with more people in the industry. Of course, you could also outsource this part of the business by partnering with a rock star broker who's willing to work with a new investor without much money of their own, depending what you're bringing to the table in terms of value.
Door knocking, writing letters is free, checking public records, and networking are all free beyond the inevitable time, energy, gas and postage costs that are associated with the effort. Perhaps find another investor further along who has systems in place in your area and see how you can assist them in building their business, and you get the education and system training as part of the deal, and negotiate a percentage of the deal at closing as you find them for the investor.
