i'm wondering if i invested to fix up the place and make it very nice, and wanted to get better tenants, what would be the most i could charge rent in that area?  

Liens may have been wiped out in the foreclosure depending on the laws of your state, or there may be a limit to how much the HOA can charge after a foreclosure. 

The company is outside of Chicago and they ship free and do not charge sales tax. 

Have the buyer put 20% down and charge them a higher interest than you pay a monthly in PITI. 

Also if and when you decide to move out the unit would be able to charge market rent.

They still charged me an ~$300 fine, and gave me the privilege of having to take additional time off from work.

There are many customer service businesses that send you birthday cards, waive your first late fee, or overage fee, send you gifts around the holiday, etc.

Do the DSTs disclose how much they charge or the transactions are non transparent ?

@Andrew Lydon, you have probably already done this, but the most important first step is making sure you pay all of your property expenses out of separate bank / credit card account(s). 

In my market, I actually use the national ones because my local guys were all charging 12% and 3-4pts.
