Hi Paul,I'd say the house is a Class C (it looks like 1982 inside), and the neighborhood might be a B- (maybe a C+) -it's hard to tell with just google maps views.You have to compare it to what else is around in the city to figure out where it stands.Ask a few local realtors what they think of the neighborhood ABC (???)

ABSOLUTELY, I'd argue strongly to invest where you live.

I love real estate investing (not hating the player here) but the reasons why it has worked so incredibly well are immoral I would argue.  

Other books you may enjoy would be 7 Habits of Highly Effective People (a must read), The Richest Man in Babylon - Original Edition, Ken McElroy's ABCs books (there's a few), What Every Real Estate Investor Should Know About Cash Flow by Frank Gallinelli, The 4-Hour Work Week by Tim Ferris, Tax Free Wealth by Tom Wheelwright and you can't go wrong with any of the books in the Bigger Pockets Bookstore - some get a little redundant but are very good.

If they violate the agreement, and you allow it to happen then one can argue that you are setting an expectation that this is ok and it's harder to go back in the other direction. 

If you have to ask this question, then I would argue you're probably not experienced enough to handle an eviction.

I’d argue that after accounting for acquisition costs of new properties, it’s hardly worth selling a property to “only” get $40k out.

Whether it be your personal budget or your business budget, I don't know any successful individuals that their business does not have a budget in place and would argue that most wealthy individuals also have a personal budget in place as well. 

Walls are still shared and depending on where the unit is I would argue you have less privacy.4) Condos are great for starting, but have its challenges.

Is this unfortunate - absolutely, but I would not recommend spending money on an attorney to try and fight it, especially since it’s not on the property and most likely it’s a public project which the seller would argue it’s also public information.
