This is a good concept, but to translate into a game, you have to have some core mechanic that holds it all together.  

Wife to an Army veteran/marine biologist/mechanical engineer/healthcare administration executive.  

You can check at the courthouse for recorded mortgages etc, but there are liens that may not be possible to determine such as an unfiled mechanics lien.

I could potentially purchase one mobile home all cash, but renting out mobile homes is very difficult: high vacancies, low rent, and high HOA costs for utilities. 

He alerted me to a mechanic's lien on the property for $25,000 (5 times the tax value), which gave me several days panic until a lawyer friend explained that these liens expire after one year unless a separate suit is filed to enforce the lien. 

I am newer to mobile home park investing and I just put one under contract because I was thinking about purchasing it but the more I do research, it seems like a bad idea.

Heck yeah good mobile home deal!

If I ask somebody how the mechanics of an airplane works, they will start by saying " I'm a broker in Texas"Everybody thinks they are a good agent just like everybody thinks they are a good driver. 

Another thing to consider when making a website is most traffic these days is all mobile traffic so make sure your site is mobile optimized.

You did not mention any payment issues, have you been collecting mechanics liens with each payment installment?
