@Calvin LipscombWe typically allow an hour for each unit - some of that time will be spent on common areas and the exterior - occasionally more.  

I am in the process of closing on a primary residence through conventional financing.I have a unsecured line of credit, that i occasionally move money into my main checking account, when I pay contractors for work on rentals etc. 

That is fine if you are flipping because that is the proper treatment there, but it is a major problem is you eventually also have rentals that you occasionally sell (you also cannot 1031 inventory, so dealer status is also problematic there). 

Occasional reader of BP finally deciding to join after my last project.

While experienced investors have occasionally found the 'diamond in the rough', it takes a lot of looking, knowing where to look, having extensive contacts (of the right kind), and the knowledge and experience to recognize the real deal.  

I follow them on social media etc so I can monitor their world with an occasional comment etc but don't attend their events, Birthdays etc.

I see these kinds of properties occasionally.

We also look at doing occasional flips or building houses from ground up.

I have multiple tenants that pay Bi-monthly(it's written into the lease) and I have to send the occasional Pay or Quit notice, but as of right now, I collect 100% rent owed to me, and I haven't had to turnover a property due to lack of payment since one of my first inherited tenants failed to pay.There will always be bad tenants, and there will always be fantastic tenants, but most of us will find, OK tenants, and it's my belief that it's your duty as a property owner to try and work with OK tenants.

I still have to occasionally remind my wife that it is all good debt.But never lose site of the fact that investing is still very high risk.
