It could really help to knock out some of your mortgage payment. 

The deal isn't a knockout, but looks like the numbers should work. 

Considering the unit is occupied, should I simply start showing as is to see if I get some interest or do I just knock out the upgrades prior to the busy season for prospective tenants?

You could then take the $300+/month your saving and knock out that loan in short order.  

However, I found that it is usually the end of the first week, and then RIGHT before the auction (which may knock out a lot of the properties you researched).   

The numbers on the deal look good and I believe this will be a knockout opportunity.

Unless the property is just an absolute knockout deal, you probably won't have much luck trying to wholesale someone else's wholesale.

Roof costs say $8000 (depending on size, shape, type of shingles, etc.) and last 25 years (depending on weather, type of shingles, slope, etc.) ... that's $27/mo you need to put away in CapEx to eventually replace the roof ... now do that for all the systems in the property, add them all up, add some reasonable amount of margin, and you have a reasonable grass roots estimate of what your CapEx should be ... code it into excel with the approriate parameters such as square footage, number of water heaters, etc. and you can knock out a CapEx estimate for a specific property in a matter of minutes, without messing around with bogus rules of thumb like 50% rule or 10% of gross rent, or any other such thing that tries to relate things that are completely unrelated in order to shortcut around actual thought and analysis.Any calculator that you do not understand all of the inputs, outputs and assumptions that went into them are less than useless, and BPs are no exception ... therefore the best ones will be the ones you build yourself from the ground up and modify over time as you gain experience and find that some of your assumptions, inputs, and formulas need tweaking.  

I don't have any empirical data, but I've got to imagine when you knock out a large percentage of the housing, the remaining stuff that is habitable is going to be more expensive for awhile.

At the moment my goal is to invest in a SFR by February, 2018 and cashflow at least 100$/m and build relationships with agents, inspectors, and property managers to invest from a distance and offer anything I can to them to even just learn as much as I can.Hearing all of the obstacles people have faced and still coming on top of it, I'm very motivated to knock out at least one deal with my 6 months here in Little Rock.
