To play into this matter, the answer is due to the free market and the principle of supply and demand (Carlos' point).

I'm not that professional but I think a whole house filter would filter particulates like dirt but not chlorine. for chlorine you might need a reverse osmosis system for a specific drinking water tap to eliminate the taste as it's not practical or efficient to put an RO on the whole house supply. if skin issues from bathing are a problem you might need a softener. sometimes when kids have eczema doctors actually prescribe "bleach baths" where a small amount of chlorine bleach is added to the bath water. also many of the water treatment systems can be rented so maybe just rent it while they are there. regardless, proceed with data. water test, pediatrician diagnosis (if it's legal to ask for, no clue), and a system that is right for the application. sounds like the tenant is willing to help out which is awesome.

in our market land is a 12 month supply. unless it's entitled it's impossible.

Have had crew's up to 9 men.It's almost a full time job just supplying product,  let alone babysitting them.9 men can do 4-6  four Plexes in 6 weeks .But ,  yes it took half of my day to and 2-4 hours every morning or evening getting product.Every one of my guys were, self employed for the daily work and paid cash every Friday. 

I've heard of mentees who started cleaning up construction areas on a flip at the end of each work day or picking up supplies at Home Depot and delivering them to the job site.

I'm an agent, so I'm not anti agent/broker, I just think there is a lot of housing supply frozen in ice because sellers need a real partner to work through various issues they have before they can sell.

I run a kitchen design and supply business.

How do you assess the overall investment climate for multi-family properties at present, considering factors such as interest rates, economic indicators, and housing supply dynamics?
