@Georgy CherkasskyIf you truly desire to become financially independent you should learn from the experienced, successful posters on this forum instead of “shooting the messenger”.  

Personally, I advocate for a long-term investment strategy and would recommend investing the funds, provided you are comfortable with the expected return on investment over time.

Even if you personally have just a modicum of design aesthetic sensibility, after reviewing 20 or 30 properties, you will quickly be able to get a sense of the winners.My 2 cents,Mike

I was specifically interested in his 2nd plan which was "Building wealth through single-family homes" where he basically says you save enough to buy your first property along with enough for other fees and then you just keep saving the money you make from that property along with some money you save from your job and once you have enough money you buy your next property and then you basically just keep repeating that until you have your desired amount of properties.

Personally, I'd go with the As-Is scenario.

Required good credit, adequate reserves, full doc commercial loan with a personal guarantee.  

This is a very personal question that is difficult to answer. 

I have a situation where a person I know is moving out of the country and would be looking to put their home for sale in the summer.

Be prepared to follow up multiple times, using different forms of communication—calls, emails, and if possible, in-person visits to their office.

Find someone where there is a personal connection and at some point your relationship now or later can benefit the mentor.
