The ones that build out great companies build the skills, then they teach the skills to people to set calls for them, go to appointments for them and they continue to build out their company as a marketing/sales operation that is more fluid to create more revenue. 

Dominated by about 7 tech non physical product companies.  6.  

However, I noticed that as a Costco member, they also offer HVAC services, including the same product line (Lennox), along with a 10% Costco Shop Card if you go through them.Has anyone here used Costco for their HVAC needs?

You'll have access to owner occupied loan products, therefore saving on your down payment, typically 3-5% compared to 20-25% for non owner occupied properties.

I could be wrong but I am unfamiliar with any products existing.

Quote from @Devin James: Gross Margin is an important calculation for developers/builders.Gross Margin = Gross Profit / RevenueWe shoot for a 20% gross margin on our New Construction HomesReal #’s:Home Sales Price: $374KClosing Cost: $18,700Cost of Construction: $258KLand Cost: $30KGross Profit = $67K$67K/$374K = 17.9% Gross MarginCame slightly short of our goal of 20%Homes Values and Build Costs are constantly fluctuatingI wish we had a crystal ball build larger homes. average new build in our market is 2200 square feet, 4 beds, 3 baths, 2 car garage and sells for 515k. construction costs lower if design is good and find the median or average home sale price and push that up. my guess is you built too small. 347k is cheap. we target 429-479k price range in columbus ohio for single family homes and also only purchase close to urban core where premiums are 20% higher and we build smaller like 1500 sq ft where price per square foot goes up. 

Here’s what you need to consider:1.Related-Party Restrictions•The IRS generally doesn’t allow 1031 exchanges when both the sale and purchase involve related parties, unless both properties are held for at least two years after the exchange.

I have been on BP a long time and maybe about eight years ago , a person had a small chance of finding a posted house for sale here that can be flipped.

You didn't mention where you are operating, but depending on average home prices, I think you'll be ok.For instance if we're talkin $500k homes, and if you will get a 2.5% commission, split that 50/50 with your Broker, you will end up with $6,250 per sale, right?

Take your sales price, minus selling costs, minus any capex, minus purchase price and that’s your taxable gain.
