How will the installment sales impact capital gains? 

I did see that SB7 said that multifamily properties would require submeters installed in every unit.

I have 8+ units that I would like to install plank flooring/vinyl of some sort when the units turn over tenants.

So you need to rip the pad out, then clean and dry the carpet, then install new pad.

If that is the case, I'd get some new ones, stack them in front of the old ones, and get rebar or similar strong metal poles pounded in to hold them in place.  

Is that fraud- no. its like someone wanted to charge me $1000 to install a dishwasher.

But per lot it will cost roughly the following:$1,500 Electrical poles, meter installation $2,000 water taps and connections$5,000 grading and land prep$8,000 septic installation (assuming a 1:1 ratio of homes to 1000 gallon septics)$5,000 down payment on each home ($700-750 / thereafter per unit)$21,500 total set up x 17 = $365,000Ongoing expenses after development would look something this for POH model: $12,750 a month in mobile home mortgages (17 x 750 for PITI on each unit) $1,900 a month in land mortgage PITI (house) $3,000 a month landscaping$2,000 a month in reserve emergency fund$2,200 management$21,850 a month total expenses $262,200‬/yearOngoing incomes after development would look something this for POH model:$27,000/month ($1500 x 18 {17 mobile homes plus house})$324,000/year324k-262,2k = 61,800 net pre-tax profit or $5,150/month.Opportunities to reduce start up expenses: Bulk deals with the government or contractors for doing all the work at once (electrical, water, land grading, septic) Trade free rent for someone to mow and landscape (turning a $3k event into a $650 event every month).

There are many others out there who would love to rent your empty unit.Also, I agree with others, install a washer/dryer if it's standard for the area. 

you can do nothing or spend tens of thousands of dollards installing sound isolators.
