Introduce yourself, give them a card and let them know you are managing the property and want to make sure the tenants behave as good neighbors should. 

The current web/app based services are all handling credit card transactions primarily.

or send letters and post cards ?

Funding sources I have used are , Credit Cards,Lines of credit on my home,borrowed from hard money (Family).Income tax refunds.

@Ryan HanrahanA private money lender will not get you money for a down payment , but you do have the option of using vehicles like Perosnal loans , credit cards ,and lines of credit which would essentially allow you to buy the property with none of your own money.

It's an industry where you can reap good benefits, if you play your cards right. 

No car loans, school loans, credit card balances or anything like that.We have little cash currently for a down payment on another property and have been trying find deals where that cash can chip in for a flip (with a partner) to start gaining small returns and build it up.I think I’ll have a hard time finding good contractors that won’t eat into profits.

I have ran the numbers with my peers, real estate agents and a couple mentors which all seem to check out.However, I’m not sure if I can qualify to rent these areas.I have not been working for 2 years, held a credit card for more than a year, etc.I have the cash amount to rent this place but as a student without any history how do I qualify?

It’s a free way to boost your score faster than just paying off a credit card on time

Often, it isn't real great - it's like a store credit card with high interest - but it might help spread out the cost a little.
