I analyze a few condo with 25% down payment and it is always giving a negative -$200-$300/month.Where should be an good area to invest in Dallas, or where else. 

However be aware these types of people usually file motions and to continue to exploit legal loop holes, in order to stay in the property longer, so take no prisoners. 

Usually small to mid-sized lenders in the area of the property are your best bank types to reach out to.  

I transferred my credit card debt with 21+% interest into balance transfer credit cards allowing me to pay off my credit card debt without paying interest (that would later negatively effect my credit score, little did I know, due to opening new lines of credit--C'Est la Vie!)  

For what is usually a minimal fee you get education from people who have "been there and done that" and, equally as important, the opportunity to network.

Usually it's because the floor was trashed beyond repair, but sometimes it's a homeowner who just couldn't be bothered.  

It depends on the area and what they are managing but usually its anywhere from 70 to 100 percent of the first months and 7-10% based on the area and whats being managed.  

The rent z-estimate is usually fairly accurate.

They usually deal with a lot of banks (like you're attempting to do on your own right now), so they have an idea on who can best service whatever type of loan that you need.

Rents usually go for $800-1000+!
