Is it common to charge more?

I used Hostify and you can work it into the management system to figure and charge all of that for you.  

How affective are physical mail cards with deal machine?

I charge $50 per side in my duplex.

When I first started out I purchased everything with 20% down and had enough available much through credit cards which can be problematic also to withstand a few months of vacancy or a $10k repair.

I charge a scaled pet fee based on the size of the dog with a premium for high risk dogs.

Charge the tenants a higher rent rate and include utilities with their rent.

Sometimes they'll have gurus come thru that charge more for a full day class or more extensive training.I've posted before some lists of area meetups...each has a little different twist and following. 

I am considering doing this with a 0% APR credit card to avoid a loan. 

My interest rate and purchase price wouldn’t allow for positive cash flow unless I charged an unreasonable rent—or put about $500K toward the principal, which isn't ideal.I’m a high earner, so I’m weighing my options:Take the loss ($60K-$100K), buy another house, and chalk this up to a hard lesson learned.Refinance, put more money into it, and rent it out long-term—even if it’s not immediately profitable.Invest my money elsewhere and try to make peace with staying here for several years or just move.Would love to hear thoughts from anyone with experience in real estate, financial strategy, or noise mitigation.
