@Brian Ellis re: your routines, it won't be perfect but as long as there is progress every day you'll continue to like the feelings of progress and will optimize so they get better and better. 

In a perfect world: (in no particular order): Square/rectangular shape, 1-story, open floor plan, lower pitched roof fully trussed, slab on grade monolithic foundation, 24 o.c framing everywhere, T1-11 plyw. siding, minimal windows, minimal doors, minimal trim, minimum code electrical/HVAC/plumbing, carpet everywhere, avoid tile, laminate countertops, Home Depot cabinets, basic fixtures and appliances, no fencing, no trees or old stumps, minimize landscaping, minimize driveways and walkways, forget pavers, cleared flat lot, no fill, utility hookups available in front of house and best case they are aleady tapped, inspectors are easy to work with and pass everything the 1st time, subs show up when they need to and actually care.

If everything goes perfectly it takes you 3 months.

Even if it don’t work out perfectly you are now an experienced investor making you leaps above many other folks here on the site!  

What you are saying is assuming that everything looks and good does not consider any vacancy, especially unexpected vacancy and that the future times are going to be perfect. 

@Eric Fegan, What you're suggesting is perfectly doable. 

@Cat R.It’s perfectly fine to enforce that right ?

Account Closed this is always an important part of due diligence on small multi family properties, and in my experience there is no perfect method.

@Jorge De Jesus perfect!
