Anyone have any tips with purchasing a landscaping company?

I'm looking to hear any tips from someone who has purchased a landscaping or home service company. Me and my husband have been thinking about it a lot recently (he has more experience and knowledge in that vertical but I have sales and marketing experience) and we feel like that would be a great company to buy. I have been wanting to pursue this for years but ultimately have prioritized my full time job as well as other ventures, and now I'm wanting to take it more seriously. However, I'm feeling a lot of imposter syndrome and not sure what it takes to buy any business (in terms of time, capital, skill level, etc)-- so would love any tips from someone who has been through it. Bonus- tips for seller financing as well. TIA!
