Best Way To Finance Additional Rental Homes For My Situation?

[Tushar Pati]

New to the forum, not really a new investor but I've been a cash buyer in terms of my investment income properties. I own 4 investment homes worth $500k give or take, all paid off no loans. I would like to buy more rental properties but I would like to finance them and I'd like to know what my limits are and what options would be available to me as my income is capped out loan wise bc I struggled getting a loan on a vacation home for myself last year. I barely got it through, but had to put 50% down. I make a lot of money but my taxable income is only $14,000/mo last year bc Im in the gas station business there is alot of cash and deductions. Anyways before I talk with a mortgage officer later this week, Im looking at some commercial as well as residential options and I'd like to know what the best options would be residentially for my situation. 

My Assets

Personal Residence - $1.4M value, $260k mortgage left

Vacation Condo - $600k Value, $240k mortgage left

2 pieces of land paid off - $300k total value I paid but taxable value on tax roll at $180k

4 rental homes paid off - $500k value

My businesses techincally have no value bc im a franchisee who just leases stores, I own nothing but the stores are not worth $0. Are there any options for someone like me with my balance sheet to borrow and buy rental properties bc I think my vacation home last year was such a struggle to buy and I had to bring alot of cash to the table I didn't want to bring into it, just looking for a way to add more properties using more low interest money
