Specifically, I’m looking for insights on cost projections, especially whether the cost per square foot tends to decrease with larger projects, and what budget I should allocate to ensure this development is profitable.Guidance from someone with experience in similar projects would be invaluable

To give you some perspective on what those tax increases can look like here are some examples of the changes based on some of my properties that I own in the city:$4096 -> $5522 (+1426)$3850 -> $5516 (+1666)$3835 -> $6283 (+2448)These are only some examples, but all of the properties that I own have increased in its tax assessed value, therefore drastically increasing the taxes per year and decreasing annual cash flow.While tax assessments are normal it seems that this is a very drastic effort to recuperate losses.

I hope so, in the last week we saw a decrease on 60bps on both the 5 & 10Y yields. 

So $100/unit decreasing in inflation adjusted dollars with time and a property loosing value in inflation adjusted dollars.  

This is not complicated folks, what happens as affordability to OWN your home decreases?

Don't get into something with inadequate cash flow and bank on the appreciation on the sale. 

So the interest payments decrease over time and more of your fixed payment goes toward decreasing principle. 

Maintenance costs don’t usually decrease over the years, so if you go with landscaping that needs care, expect your costs to increase over time.

Since values have still remained strong people are still cashing out further decreasing supply. 

I would guess between $600-$1,000 annually would be a good estimate for a rental house based on what I have in my portfolio... so I would decrease the $187/month to about $80-$100 per month.
