Each site you evaluate is another step forward and you'll learn more along the way.

More specifically can you get utilities to the site?

but I suspect homesites will drive the best values.. no one wants logged over sites for building ( generally speaking)  it works here in the Northwest because of the incredible shortage of buildable land. but in other areas not so much

Quote from @Hector Espinosa: Hi,I'm negotiating a seller financing deal which may be my first one and would like to ask for some advise about and what are advantages and disadvantages about seller financing deals.These are the seller financing terms:House Price: $330,000.00 USD​ (Sellers still owe ~$301,000 USD)Down Payment: 5% = $16,500 USD​Loan Amount: $313, 500​ (Monthly payments will be amortized as a 30 years loan​)Interest Rate: 4.531%Balloon Loan Term: 5 YearsMonthly Payment (P&I): $1,594.24​Closing Costs:  ~$3300 ​Zip Code: 74105Observations:       * HVAC requires an update but pending to inspection (replacing with a new one will cost ~$10,000 - $15,000 USD )     * Expected Rent Income: $2,000- $2,300 but this is has been really complicated to get a good estimate because is all over the place in the different sites I have checked

Happy to have found this site. 

I do occasionally post about it on some of the social media sites for travel nurses, such as Travel Nurse Gypsy Housing for example. 

Just make sure everyone understands that they will be on the site for anyone to see.And no minors.

Its generally retail medical operators, so we include things like the market dynamics for our use and why statistically the market and location of the site will be viable form a business case standpoint, and speak to how the startup has enlisted the help of an EMR or other such consultant to help in their general rampup and ability to bill/get insurance contracts.  

I think tracking productivity will be tough unless you have someone on site that is checking their work at the end of the day and documenting their progress. 

Quote from @Chris Seveney: @Zach EdelmanBe clear BP does not recommend companies - companies pay to advertise on BP and while BP I assume vets them - it’s still buyer bewareI am not an employee of BP but I want people to understand on BP and on most sites there are sponsors and affiliates but they may not be thoroughly vetted.
