You'll get differing amounts and qualities of leads depending on the type of marketing, but also depending on who you're marketing to and where.

@Eric L ConryThis is a highly personal choice.

I am a general contractor that specializes in kitchen remodels and high end custom cabinetry, but I'd like to use this project to pivot into more general contracting and property development. 

Most CFO clients that I work with that are new construction/home builders usually target a 20%-25% gross margin as they usually have to deliver high teen returns to their investors.Great question. 

I have an outdoor pool that easily have 1k+ people using it every season and I never had single complaint due to the water quality.

And for an OOS, I always advise to keep things simple at start, don't get greedy, go for quality and consistency, then work on maximizing monetization later. 

I highly recommend consulting with a CPA or tax professional to ensure you're using the best strategy for your situation.Good luck!

When investing in high cash-flow markets, I always recommend working with an investor friendly agent so you're able to gain the right insight on the different areas and the risks involved.
