That seems artificially low.* Why is the loan term 25 years instead of 30?

You must know your market, operating costs, ROI, trends, and be able to speak intelligently to these things and more.

The space is fairly well lit with good windows, and also has ample artificial lighting.

For example, in San Francisco, I see a 4 bed 3 bath house sold for $650k when the homes in the area normally sell in the $3M range.The one example I'm thinking about is when parents "sell" to children, they will artificially lower the price.

10% is a reasonable rule of thumb for many.I think what @Marty Boardman said was intelligent, i.e. asking a prospective private lender, "What kind of return were you hoping to get?"

Unfortunately for new dudes like us, we can be as smart as we want, but it's our time in business that may be slowing down (which you can't control... you can control your level of intelligence though).Hopefully all this makes sense and I'm excited you asked this question because it shows you care about those you serve!

Anyway, the best way to find a buyer for a vacant parcel is to put it on the MLS, so we "whole-taled" the ones we've done, meaning we closed ourselves with our own money on the vacant lots at what we knew were a decent price, i.e. 1/3 or 1/4 of what the vacant lots around it were trading for, and then we immediately put it on the market, however in an intelligent and professional way, meaning we knew the exact details of the zoning (most listing agents are too lazy to figure that out), utility availability, drone/aerial photographs, etc. 

I'm more concerned about this growing idea that artificial intelligence (AI) can answer questions for us.

Personally I’m just tired of spending my time building other people’s businesses and I’ve watched several small business owners I worked for over the years become financially free and  These were typically poorly managed companies ran by men that I feel were less intelligent than me . 

Bob can be described as someone extremely intelligent but unable to keep his intelligence on topic.
