Because I didn't buy the property with the intent of using the BRRRR strategy and it is probably apparent in the numbers but I intend to re coupe as quick as possible and my next property will be using the BRRRR strategy so I can invest quicker than I currently am because my current plan was to purchase a property a year but I want to promptly ramp it up to 2 per year  for the next baby step and I am just trying to find the best strategy to ramp it up!

Doubt you can increase the rent, but will have a quicker turnover between tenants but you will increase the service calls if you are not careful.

Might be quicker and easier to just pay out of pocket, get it back to market and producing income again to recoup some of the losses3) Cannot help you with attorney - but yes, you should do all of those things - over the years we have had enough of these cases and sent them to collections that now it is another monthly income stream4) Yes, it will not hurt, then you will have it depending on the avenue you elect to pursue to stabilize it
