(It does not have to be empty of personal property).  

@Kristi KandelI was just letting this person know the reality of their situation.

We all love the idea of the elusive off market deal, but if you are just a person who buys real estate rather than someone who has a real estate business, don't get cute.

The personal credit card options, such as the Amex Gold and Platinum, are perfect for frequent travelers as they quickly pay for themselves with travel perks and rewards.For real estate professionals, the new Hilton Honors Business Card earns 5X points on all purchases up to $100,000, while the Blue Business Plus Credit Card offers 2X points on all purchases up to $50,000.

You don't have to meet them in person.

I personally like the Chase Ink series of cards as I use Chase for my personal cards as well. 

Provide Ample Notice: Regardless of legal minimums, giving your tenants more notice than required can help maintain a good relationship and give them ample time to find new housing.4.

I have a real estate portfolio with good amount of equity (most of the portfolio is free and clear), however my personal DTI ratio is too high and that's stopping me from tapping into it to settle some debts and buy more properties.

I haven’t come across that before personally so I was wondering if that’s a good thing or a red flag he’d be offering that?

Having a relationship with an investor friendly and proactive Realtor can't hurt.
