I am in a physically demanding career and if I was able to work, I would like to replace my income.

I flew up to Reno once.. and had down time and lost all my money at the casino  ... and did not have cash to get my car out of the park and fly.. ( pre credit card days )  LOL.

In an abbreviated list we would have to look into the physical property, the title to the real property, the credit worthiness of the borrower - past and future (includes performance), servicing of the loan if originated, the paperwork the loan was originated by and regulatory and compliance issues related to the loan and borrower.  

Every morning he'd get a fax in with all of the updates to listings and then have to go into this gigantic binder to physically take out the old property sheet and put in the new one.  

Be very aware of your surroundings, definitely setup a way for your renters to submit payment to where you don't have to physically collect.  

You have two choices, hire someone who is willing to teach you how to estimate (online or physical), or self-teach by buying some books like J Scott's book or Construction installation encyclopedia.

First of all, there is physical appearance and second there is how you act towards people.

the deposit is for damages, financial or physical, which are ultimately the same.  

I have many physical issues.

You can't always base your analysis at what the MLS data shows for rent but physically go look at it and see what you can do to increase rent to make the numbers look good.
