For mine, I live upstairs (2 bed 2 bath) and rent the basement (studio/1 bath) as a furnished mid term rental. 

Amazon has no end of them.

I have a client that uses Amazon Business Prime through Amex and they get some pretty good points off of it.

You can buy a boroscope waterproof camera off Amazon for < $100.

I am surprised I haven't seen any forum activity yet on Engelo Rumora's recently published book The Raw Truth to Success In Real Estate, available on Amazon.

I also have a book i wrote on the topic on Amazon if you can find it. 

The amount of repairs and updating required will vary depending on whether a bedroom in the home is being rented, a basement or attic is being remodeled into a studio apartment, or extra units in a multifamily property are being updated. 5.

Do we still get the bonuses if bought on Amazon/Kindle?

Seems like a very hard question to get ansewrs for, it really depends what includes in that renovation, i cant speak per sqft but i can tell you from my experince what i paid/paying for diffrent types of reno, Just tenant turnover with very cosmtic reno, like sheet rock, paint maybe a few lights for a studio/1 bedroom 2-3k, For a little heavier simalr unit probobly 3-5k, just is just labor, for a 2 bedroom unit needs new kitchen, bathroom, back door and probobly 5 windows, i think it will cost me closer to 25k-30 including metirial, now i have a full gut just outside of pittsburgh that a 3 bedroom 2/3 bath that i am probobly gonna end with 100k reno,Hope this helps, good luck

Amazon HQ is coming to our area (DMV) and condos are flying like anything.
