I look at my return on the investment only factoring the interest portion of the mortgage payment but use the cash flow side to get a better idea on how the property will work with financing and scalability.  

Factor your repairs into your price and go for it.

@George Blower Thanks to you as well, however, I am curious if "metals" factor in such precious metals as gold, silver, platinum, etc?

I used to factor companies' receivables.  

This way if it was more time consuming, we charge more, but at the very minimum, a $150 fee will be charged.When factoring the cost, make sure that it covers the minimum time just to make it worth it to someone to do the work. 

That with the building of the new police building and other factors help we decide if or when to get involved.

If the total debt is $651M, there isn't any equity to chase or protect, especially if that is the "balance" (Which doesn't mean that is the payoff, when you factor in foreclosure fees and costs).

I am an electrical designer and I have my LEED Green Associate Credential from USGBC.

@Ramzi Nuseibeh yes, you can have more than one property and should hold that money in a designated account separate from other funds.

@Tom Smith Just make sure you run the numbers factoring in the taxes.
