What kind of debt cc student loans etc and at what rates?

My sister has 22 properties in the Pitt area but does her own CC and asks for Proof of income (meet 3x rent).

Mortgages, lines of credit, checking/saving, or CC's? 

Is there a good CC with an app that maybe allows me to take photos of receipts?

I find tenants like being able to schedule payments ahead of time as well as pay with CC as needed.

@Zach Schwarzmiller   having lived in Napa ( Silverado CC) were many winery owners lived and I played golf with them for years...

Our combined income is mediocre to say the least (85k/year, soon to be 95 - 100k) and have one car payment (300/m) and some cc debt (10k).We felt that we had a a unique situation on our hands because of the equity we have on our home, so we decided to do some researching in Real Estate investing and came to the conclusion of doing a HELOC and investing in SFH in Lancaster or Palmdale, CA.Chase, our lender only approved us for 40k with the condition to pay off our debt and car loan which only leaves us with around 6k.We are thinking about Lancaster and Palmdale because there are some properties that will fits our budget and fall within the 1 - 2% rule.Any advice?

one side needs some cosmetic and appliances and the other needs some work (there was a leak at one point and the ceiling is a mess).Question - To do this I'm going to pull funding from a few sources (401K, Savings, CC, mortgage).  

I have a Lowe's CC and get 5% off of all purchases.

I have borrowed against my primary residence and even raised my CC limits in the event if I was to use them.
