So in a three year period (which is the average stay) you will spend at least $950 tenanting, $475 renewal, and $1100 improvements divided by 36 months. 

Asset dissipation works like this:  when purchasing a primary or second home with 20% down, Freddie allows total assets (some restrictions on type of assets/age/etc) minus cash to close to be divided by 240 months to get a monthly "income" number.

Always make offers below market value at a price that will make an equity,sell or renovate ( It is imperatives to know your comparable and compare prices, Square footage and condition, calculate the cost per SF) compare dollar value (divide SF into asking price to get cost per SF) Ask "Can you help with financing", even if you get a NO, ignore that and make it a contingent in your offer.

So if the owner owed $1000 in back taxes then $1000 in interest is the most they would have to pay as long as the auction price was high enough.SC pays up to 12%, so if you divide the amount of taxes owed by .12 this would tell you the most you should pay at auction before your interest rate starts dropping below the max allowable.
