Measuring if a property is a reasonable first, second or last investment is not a function of how much you have saved.

@Marcos Altamirano Toriz -  in todays corporate IT world,   the game is leveraging "out of the box"  application functionality by "configuration" versus "customization".   

A realtor's job is to properly advise you.

The rest "should be" (if bought properly), paid for by someone or something else. 

Take ownership of your mistake and learn to do the proper due diligence recommended above😊

If so, make sure agreement is in writing, signed by both parties, specifies new end date and ensures any existing security deposit will still be dealt with properly per landlord/tenant laws, and I'd also ask for a partial payment to be issued at signing to make obtaining his new place easier.  

They also do not have a proper screening process for tenants.

For newly constructed, purchased or renovated properties and also retroactive generally over the last 10 years, building components are properly classified into individual units of property and accurate recovery periods for computing depreciation deductions.

Rotting window frames, unsafe electrical issues, a tub and sink that didn’t drain properly, a promised dishwasher that turned out to be broken and unusable, a driveway with tons of pot holes so deep that they could have easily damaged cars, and much, much more.

Without having the facts it sounds like there was not proper notice to the estate.
