From there, I was able to keep rolling my funds back into projects and keep increasing the margins. 

I would like to know which sites are reliable to do some market research on population growth, and income on zipcodes, and counties in Delaware.

I did all the labor and will have to come up with my labor worth (Finalizing this number but its in this ballpark)$3,575 Current Rents > $2,545 Previous Rents (40% Increase)             - Unit 1 $595 to $750 - Unit 2 $650 to $900(when I move out) - Unit 3 $650 to $1075 - Unit 4 $650 to $900$360k - $400k ARV > $380k x 75% = $285k - $225k = $60k Cash Out?

We cash flow on average $3K a month once leased on a 3-5 year commercial lease with increases built in.

There is no increase in value, but if you want to use the cash in the bank, it's free...not so if you transferred it to your property. 

In short it doesn't matter if you increase how much income a residential home is leased out for that will never improve your property value it's always based on how much homes in that area sell for. commercial real estate on the other hand has a few other ways properties are valued including the income approach.

I want to increase my personal income to help fund a second rental, but my career limits me mainly to remote jobs and gigs.I’m curious if there are any other investors out there that started with a similar skill set to mine, and what other skills they developed to help increase their W2 income and to help build their real estate knowledge and experience? 

Draw the line based on what is the return for each. if it costs and extra $40k to get you $40k price increase it is not worth it, it has to add value to you.

If you already have a track record, they might consider something small which you can then increase over time. 

And the demand is only going to increase incredibly over the next two decades due to demographics and lack of supply and building.
