My thoughts are....Reorganize the homes into a well thought out , functional, and aesthetically pleasing layout.

The NPV is the Net Present Value of an income stream, discounted to the cost of capital (or required rate of return) and the IRR sets the NPV function = 0 to get a rate of return.

I honestly think the largest problem with affordable housing right now is the city not supporting increased density.

The article does not specify the latter.As of Q1 2020 based on historical price income-ratios, I see only 11 out of 50 largest cities (by population, not inventory) overvalued > 10%.

The question is why develop a park when you can buy a functioning one for less $ per lot and with positive cash flow?

My personal big mistakes have been - buying home with converted garage and only car port (buyers here in So Cal, especially the guys, want/need a garage), bought a house with 55 stairs from street to front door - never again, and largest financial mistake was not going with my gut and chose to go with a new agent to list a multi million dollar property rather than my proven agent or myself.

You won't be able to use the IRA owned properties for personal use nor can you perform sweat equity functions on the property. 

NYC each borough has their own Department of buildings , each function a little differently from my experience.

Jessie Niu Seller is probably the largest highest grossing broker/builder in the area.

Not many break, the way we install tile floors.The main benefit of tile for us that Pittsburgh's largest industry is currently health care.
