Hello Komal, Welcome to BP community where you can learn a lot by connecting with people on here and reading through the forums.

I get their contact info just in case and charge a premium so if there was small damage which is hardly the case I'd be able to take care of it.

I have started to read, "The Book on Rental Property Investing" by Brandon Turner.

You can look at Zillow or Redfin but unless you're looking for something in a narrow niche, those aren't deals and won't cash flowCan you go to the bookstore and read Brandon Turner's first few books?

The diamond tenants often do not care about low rent  their focus is the best site.

I read a few discussions recently about WealthAbility and how few had any experience with them.

I have been a member but have not done anything so far, mainly lurking and reading. 

To calculate your land value, take into consideration the average price per square foot or acre of the comps and apply that to your land.Steps to apply comps to your property:1) Compile multiple comps: Find a real estate agent to help you put together a list of comparable properties.2) Make adjustments: Analyze each comp carefully to determine whether it has advantages or disadvantages when compared to your property and make adjustments to the value upwards or downwards as necessary.3) Determine the use of weighted average vs average: Depending on how close the comps are to your specific property; you may consider utilizing the weighted average method to place a greater weight on those properties that more closely resemble yours.Using comps to value your land can add a component of complexity and subjectivity.

@Justin GoodinI just read and posted a question on another post literally minutes ago. 

I have read conflicting information as to the requirements and limitations of a real estate agent being part of an LLC owning rental property.
