Currently I had borrowed 12.5k to consolidate credit card debt and I can borrow up to 23k. 2) Would it be wise to roll this into my home mortgage so I can get the tax break for the interest and allow for more borrowing power from a credit union?

this is old  tried and true method of simply having you pay them to get credit cards .. there is no need to pay for this service.. unless you want to of course.. there is no magic bullet ut there that is going to give you credit and financing unless you actually qualify for it.But zero interest credit cards are used by some to do rehab and then pay them off issue is though your fico score drops like a rock the second you take on all these CC.Also starting out there is zero chance of getting any kind of business line of Credit that is unsecured.

Highly recommend you have stripe with rental agreement where you collect identification, selfie, credit card info, and e-signature.

PadSplit is not passive but it has been a mostly positive experience for me.His numbers seem realistic except PadSplit fees are typically 14.75% (not 14.25%)which is a 12% platform fee and a 2.75% stripe fee to allow members to pay their rent w a credit card. 

This is basically an unsecured personal loan, like a credit card.

2.For purchases made on a credit card, is it best to use separate cards, or are there good methods for tracking expenses by property?

They could even log into the Google email account associated with the account and send questionable emails, upload photos of who knows what to Google photos, etc.. 

The more his students buy/sell, the more money Pace makes.I believe the entire thing is a house of cards that will collapse when the market turns.

Instead of just uploading cleaned CSVs, you are also able to upload PDFs of delinquencies or violations.

Instead, you checked out through Stripe with a VISA card ending in 1372 (expired).
