The surface is heavily highly worn, likely older than 35 years or more ?.

Even though visually it does not appear to be water tight, water tests to reveal the pool is likely water tight at this time (older / very old water).

An estimated cost to re plaster would likely run 6-10k for low quality 15 year "flip re-plaster". Vs the 30 year plaster - $10-14K + options.

Older waterline tile, original (50+ years old). Some tile cracked near the shallow end that can be corrected ($500+) otherwise in older condition due to be updated soon especially the mortar = $1k mortar and 3k+ to re do tile complete.

The coping stones around the pool are older and due to be reset soon ($1k+) and possible re mortared / some pieces replaced that are cracked ($3k+).

The water was clearly green and what I would have assumed due to be drained and cleaned, but surprisingly the chlorine being so high and algae / green walls tells me this pool has been on life support (deep end transplant intake and return pipes added in) for more than 6 months.

Id recommend draining and re filling + acid wash complete ($1500) for a most complete cleaning, which will likely be done at time of re-plaster (asap) for free.

The skimmer has been disconnected as well as the main drain, recommend budgeting 5k+ to re establish that function at time of remodel. It would be easiest to remove some decking and establish a new 2” skimmer and a separate 2” or larger main drain line at time of remodel.

Until then recommend establishing a new dual suction inlet vs the current single suction inlet for additional safety (+$500)

The main drain in the pool has been capped in the skimmer line. Indicating it is likely no longer usable in its current state. A new run will likely cost +$5-10K at time of remodel on top of re plastering

The cleaner is connected to a literal garden hose (actually a good idea if mounted in center and no actual garden hose is in the pool vs cleaner hose only (designed for in pool use with swivels).

Wheels aren't turning well when resisted, indicating service is needed = wheel and or bands or more = $105-250+

At Time of Remodel = Likely on the same side of the pool as the skimmer you install a new cleaner line which decking nearby will be opened up for this to be accomplished.

Recommend adding a new hose, and Pool Sentry 300 autofill $90 = $250 or less. There is a current leak on most of the equipment therefore re-plenishing of water is essential.

At time of remodel the south east side of the pool will be open to easily add an auto fill with at least a 1" supply and ideally a 2" or equivalent overfill.

Older style light niche with a conversion ring to 10” - light is older and will need to be updated due to water being present inside the light lens - new light can is $450+ for incandescent + install $450

A new light niche (required!) at time of remodel will likely cost approx 1K+

Older filter that is due to be serviced (leaking heavily from tank o ring) now which will include new elements and new pressure gauge, maybe a new cartridge filter band will be in order or a simple tank o ring ($80 + 250). Also a new pressure gauge $50 + maybe more likely elements ($500). I see an older filter that id prefer to move away from Jandy as their prices for items are more than they should be vs Pentair - or with any luck a Sand Filter instead ie Tr-100C or Pentair CCP 420 <- not my rec just to compare.

This pump is in working condition, recommend re doing the intake side with multiple 90's causing excess restrictions ($500+ ). Also this is a good pump for energy efficiency, so running more often / longer at low speeds will help keep a pool like this cleaner at the lowest cost.

Working but leaking at likely its seal plate / wet seal and may require a complete wet end seal update ($450+),

This is being used to power the bottom cleaner, and a new version is approx the same cost (Pentair HydroBoost) + install $450+

Functions timer and breakers all trip and reset. Some simple protection shields needed and or GFCI outlets ($200+)

Also adding a water bond is another layer of safety ($300+).

Likely a full re do is in order.
