I am in Phoenix/Maricopa County.On the letters that come back as undeliverable, I research the assessor's office, treasurer's office, etc.I have found a few properties that are behind in their taxes, and naturally, people have purchased tax liens.

It's no wonder that you are naturally aligning yourself on the commercial side of REI.

I have been involved in my dad's RE investment ventures for the past decade, they were mostly passive (investments) in nature.

I have found a home on resale for 20,000 it naturally needs rehab but I believe It is a great opportunity for my first property.

Although if you work for a commercial brokerage it is harder to build a book of business, agents are sharper and more aggressive, and it can become pretty hairy if something out of your control delays a contract or something of that nature, and on top of that you probably wouldn't be able to take advantage of the rise of the housing market [Lots of $$$$$$$$].

I do not trust markets so I am naturally inclined to buying real estate.Further, suppose I live overseas but have a friend-realtor who can find a property for me and, hopefully manage it for me.

Naturally contractors want to make money and may suggest certain materials that have higher margins but it's up to you to decide if its worth it. 

But once you can take those calculations and put them into a spreadsheet (I use google sheets) and get reps looking at homes on Zillow, realtor.com, redfin, etcetera it will become second nature! 

Heating costs go up in winter, as does electric due to the reduced natural light and people being indoors more.

Is it just the simple fact an eviction exists that I should deny an application, or should I look at the nature and facts of the eviction and consider criminal history before deciding to just deny the application because of the eviction ?
