I am always amazed how many people don't realize you need to do routine maintenance so I have to ask now

Or if I can install and maintain my own HVAC systems once I have my dozen or so properties bought the maintenance would just become part of routine management.

Hi BP,Recently I fell out of my routine of eating healthy, exercising, reading ,etc (essentially dropped a lot of my good habits).

@John Warren as I mentioned, you have to adjust the numbers based on your reality. 10% for management is the going rate around the country and may even be higher when you consider leasing fees, maintenance markups, and other expenses. 10% for routine maintenance and 10% for capex is pretty reasonable unless you have a newer home.

Check with an attorney to see if wage garnishment is an option for your area.Not to be mean but I hope you realize and learn that a routine inspection would have revealed the dogs before the damage got to this point. 

and experienced investors (what can I implement into my daily routine that could help me achieve greater results?).

You will see that as you develop a routine, it will get a bit easier with time.

Do they offer routine maintenance programs?

Is the routinely late-yet-paid rent a bigger risk than vacancy during turnover? 

there is no rule of thumb and BRRRR generally if you pull out all your cash your cash flow will be minimal.the theory is you can build up a portfolio and you suppose to have some built in equity.but the deals are not what they were 5 to 10 years ago.. so while in theory for sure this works and its not a new concept we did these loans routinely prior to the GFC  its just been coined on this site ..
