I actually have two options for this property: 1) Rent out the existing 25 storage units AND rent out the building plus add the 25 additional units out of pocket.OR 2) Rent out the existing 25 storage units and added the 25 additional units out of pocket to rent them out BUT keep the metal building for my GC business to where we have offices and storage for building materials.

I use $250/pet and no additional monthly.

Maybe the scope of work that he accomplished for you on your property was much larger than the scope of work that was bid for by the other plumber.

You'll be fine, especially if you're using additional equity contribution to improve the property before your refinance.

I'm curious if these new tech can somehow help me streamline certain tasks or reduce dependency on scarce trades in your experience.Appreciate any additional thoughts I looked at 3d printing those machines are 800k plus.. and if you watch the video you need very large lots as you have to bring in truck loads of sand etc.. so thats not really going to work in an urban environment like Charleston SC were I have built 35 plus homes in the downtown core on lots that are from 12' wide to max of about 30' and roadways that are only 20' wide and have houses and cars on every lot expect the infill..

Additionally, consulting with a financial advisor experienced in international real estate investments can provide further guidance tailored to your situation.I may also be able t find a lender besides a local bank!

The two additional units will be detached from the existing structure so there will be no interruptions from that standpoint.I have agreed to a temporary rent reduction at the tenant's request to compensate for the inconvenience and loss of the backyard during construction. 

@George Goldstein, in addition to what others above have said.

There is more to the formula on how much you can bring in, assuming you're self-employed.If you're an S-Corp, you can do the 23k as an employEE, then an additional 25% of your salary on top of that, with a maximum of $69k total. 

Just a few additional words of encouragement.
