During the 2008 meltdown, I knew of landlords who got into trouble when their tenants lost their jobs and stopped paying the rent.

Hi,    Im wondering if it is easier to borrow money  from one lender and pay it back or borrow from multiple lenders and pay them back.

. :) You could find a couple cards with zero percent balance transfer offers and move the balances to them to stop the interest charges.

He stopped  paying his rent two months after he moved in , it took another 7 months to get him out.

(That would be fantastic.)Is there a limit to the amount one can borrow on investment properties in traditional loans as opposed to private or HML?

A one stop shop and I've worked with them since 2006. 

You will need to change jobs before you will be able to stop working for someone else and no 100K is not enough.

If you borrow money you will have some other conveyancing costs and maybe points from the lender to pay. 

Be careful on borrowing from your 401(k). 

Also I am looking forward to using the income from these properties to improve my debt to income so I can borrow more to buy more properties next year or the year after, how might this be affected by starting an LLC to manage my properties?
