I've never used the traditional formulas of cap rate / GRM / ect -- However, I want to purchasing much larger buildings (20+ units) and think having a basic idea of the fundamentals is probably necessary.

I will be financing my deal through a traditional 30 year mortgage.

On a traditional bank loan, the bank sends out a 1098 mortgage interest statement to show what interest you paid for tax purposes.

So I was wondering if there is a real "soup to nuts" guide for beginning investors that are looking to buy and hold rental properties when they are starting from $0 and have no wealthy friends or family to rely on for non-traditional investment loans. 

For 1-4-family homes financed with traditional financing, don't do it until AFTER closing.

@Christian Wathne it will appraise for 265k, since I am beneficiary of the estate with my sister I could buy her out for 125k.

Get a traditional 30 year loan, put as little money down as you can.  

If you are using hard money you need to budget for the points and fees as well as traditional third party closing fees.Repairs: The money it is going to take you to rehab the property plus an extra 10% of estimated repair costs to account for unexpected repairs.Holdings Costs: Here is where a lot of investors get tripped up.

The other impact is landlords realizing they can earn more with short term vacation rentals than long term traditional rentals in driving traditional rents up.
