You timing might be awful though as we just finished one of the worst years so likely your account is down and then you would add another 30% reduction on what you pull out. 

Sand and Water proof to finish.

I am finishing a property and would like to rent it out and refinance and repeat the process.

I think you may have very well narrowed down my strategy choices down to one of three; the BRRRR method (although this might be too much to start with for a newbie), the live-in flip that you mentioned (probably the most practical as I've been part of many different projects in the construction industry), and a combination of house-hacking/live-in flip (probably the most rewarding with a potential to swap between units as I finish one in order to bring better rental income).

The architectural plans costs: $6k The city fees were a total of : $7,500 We applied for a city grant and got approved : for $20k once we finish the foundation.

This will vary based on foundation type and cost and ALL finishes- interior and exterior. 

A small number use the hot press process that is distinctly superior in my opinion in overall strength in dimensional structure and durability.Your chart does note finish which is an excellent point as it's the finish and not the wearlayer that gives a product it's scratch resistance( AO and Ceramic Bead being one of the best but it also depends on how many coats are put on which many makers do not detail).

You have $300 a month loss (again - ignoring mgmt and repairs) - you finish unit 3 in another month - by month 4 or 5 you have all three units renting for $900 a month - so you have $2700 a month coming in with a mortgage of $2100.

That almost defeats the purpose of trying to attain wealth.Regarding having a small business, you may be eligible for different types of retirement accounts, deductibility of health insurance and other things.New Jersey also has a complex tax system - It may be worth while to work with a CPA in the tri-state area.

Just putting in a glass block window will still require some finish work where you pull off the moldings.
