They are far more common now and harder to find models without but:1) these add cost to the purchase price2) they don't bring a lot of value3) they can leak or detach and damage the propertyI own around 50 doors and I cap off the line at the wall or in the basement with a valve and a cap so the potential for leaks is 0.00001% :-) 

I have never purchased anything 'perfect' but all of my rentals could have been rented as they were upon purchasing them. 

Purchase price: $275,000 Cash invested: $275,000About this homeBeautiful 2 bedrooms 1 bathroom condo in the convenient location of Rowland Heights, close to bus stop, supermarket, schools, shopping centers etc. newer counter top in kitchen and bathroom. 2 parking spaces and storage room.

Also, you are not going to be able to purchase a property subject to if you are dealing with a realtor. 

Now purchasing a home with cash is always good b/c obviously cash is king but also I think the part you might've missed is that, the money your utilizing on these home's won't actually be yours, but the banks or whatever institution you used to fix the home or make its value worth more.

This sounds like a home run and a great first purchase!!

They also didn't get hit with capital gains on the entire purchase price, which enables them to keep more of their money. 

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.
