You can build up goodwill sending grocery cards at Christmas, having a mini fridge to rush over the moment there is a problem, giving rent credits, etc. and it will mean LESS THAN ZERO as soon as you have a late fee you expect them to pay, a pet that you cannot approve, anytime the rent goes up, telling them they can't paint the walls and ceiling the color they want... then you are the scumbag landlord.

Think of it as a credit card tied to your house.

I have paid/settled everything and have few credit cards and my fico is in the low to mid 600s.I have pretty decent income ($400K+) and am interested in starting off small.

If you are pulling a HELOC or taking family money, leveraging credit cards, using personal savings it took you years to accumulate, whatever the source of money is - unless the source is endless - start small. 

You are over-thinking the process and will be sitting on vacancies as the market slows and tenants become harder to find.Get a YTD paystub, last year's W-2, recent bank statement, government picture ID and SSN card.

I suggested to Clint to stack some credit cards to have zero rate for 12 -18 months as his cushion for cash.

So how much is your w-2 income and your total mortgage debt/car/credit cards?

Some of the deal structures on these are overly complicated and involve way too many people, more like a house of cards than an investment strategy.  

I’m looking for the best ways to build my FICO score.Most likely, it will be a secure credit card, but do I need to have a US address in order my FICO score?

I shook his hand introduced myself, gave him my card and then asked him to call if there were questions or concerns.
