There are an endless supply of options out there. 

Bottom line is if you already make a lot of money you don't need the headache of low income tenants and questionable areas.If you are someone that is trying to take very little and turn it into a lot and you have endless energy and can handle the constant issues then it might be worth your time.Not trying to put any investors into a certain category but I do see low income investors more from people that make say 40,000 a year at their job and are trying for maximum cash flow to break free and live on real estate.

When I started, I listened to podcasts endlessly and read as much as I could. 

Your question is simple, but requires a complex answer with endless factors to consider.  

$XX,XXX upfront and then $xxx per month or per year... whatever, the options are endless here on the agreement side and the additional benefit is there is NOTHING for you to upkeep because again the Tenant owns the structure, lastly if there is a default and your agreement allows it you may assess penalties to ensure it does not bring down your existing property's value, and beyond penalties if the default continues you can foreclose on the structure... the structure is your security. 

I meant we as investor could play in debt portion too, maybe offering 7% rate LOL The possibility is endless.

The possibilities are endless so it's up to you to do the preliminary work of answering the following questions:-What is my real estate goal? 

Even if it's a hotlinked table of contents in a PDF, that's better than scrolling endlessly to find out how to light the firepit ;-)

I love being around Real Estate, I love talking about Real Estate and I love endlessly learning about Real Estate.

With so much access to great information including free online videos and courses, the possibilities are endless!
