I do not like having to scroll through pages of posts to see what is new.

If you go to my ACT Investment Properties, LLC Website, click on the tab "Investment Strategies" and scroll down until you see a photo.

As I scroll down I see the "Holding Costs" section.HOLDING COSTS:Mortgage Payments ($900.00)Property Taxes         ($600.00)Insurance                 ($300.00)Utilities                     ($600.00)Lawn Care               ($150.00)Total:                      -$2,550.00As I know these are estimates but when and what are the best ways to prepare for the holding costs fees? 

After I scroll down past the first "page" of recent posts it super sizes the profile pics of everyone.

I have about 5-10 ads running at all times per city for different things and you constantly have to change them up because the market gets dry and people scroll straight past ads they've already seen before. fb marketing is way more tedious than direct mail and getting way more competitive I think but in the end I only pay about $4-5 per warm/hot lead which you will never get with direct mail.

I came across this duplex ... maybe you can take the square footage from this duplex and scroll down to the "estimated value" and click on the "per sqft" tab it goes back to Aug 2008 if you hover over the line of the chart it will show prices by month and year, but you would have to breakdown the per sqft pricing....with the price and sqft listed. http://listings.findthehome.com/l/122192534/20129-...  

Are there useful tools for me to get a sense of what market rents are, or should I just scroll through craigslist rentals, and contact local agents and management companies? 

If you look up an address and scroll down on the page, RedFin will have comps for you.

Scroll your mouse over the "Tools" tab and click on the "file place" to find the article in question.

Also, enter the street name in the county tax bill lookup area; then scroll through for ownership with company names.
