Would you be interested in having a job in which you earn about $ 30,000 for each project you do? Mark Ferguson has been in the business of buying and selling houses since he graduated from college 15 years ago.

And in that time he has sold more than 120 properties, for which he has obtained that profit on average. But not everything has been to sew and sing. With all his experience, last year a builder who remodeled one of his houses did a terrible job.

It destroyed part of the structure and installed a staircase where it did not go. “It would have cost me an additional $ 100,000 to repair the damage, so I decided to sell it at a loss.” Therefore, it is not as easy as it seems, judging by some television programs dedicated to the subject.

These are some essential tips to not come out with the tables in your head.
