My advise (as both an investor and wife of a realtor), would be to use Zillow sold comps as your first analysis tool.

It is a very powerful tool, which most people don't use as effectively as they could.

I've found it to be a useful tool when working with clients.

Anyone who uses jumper cables to steal electricity should not be allowed anywhere near power tools or even a hammer and nails.

I feel like it's a tool that I need in my tool belt but I've got to be smart about where I'm allocating time.  

This site and everyone on it is a great tool.  

There are many tools and forums on this website that can help you out, and some of those forums are about helping protect landlords, the ones who have to deal with tenant issues, evictions, and may want to be protected from lashback from pesky tenants. 

I'm using the BiggerPockets tool to help with the calculations and assuming 5% vacancy, 5% repairs, $183 capex, and 11% for my property manager.According to my portfolio lender I should be able to get best rate financing for my first 10 properties by using 5 without an llc and then opening an llc and do 5 more. 

I'm not sure what I'd do without Podio or a similar CRM.
