In 2015, I paid £315K for a 170sqm bungalow on a 0.5 acre plot in the beautiful Cheshire countryside, which required a complete renovation.

I spent almost £300k on adding a 100sqm extension; £10k's worth of solar panels; 230sqm of wet UFH heated by biomass boiler on RHI (pays over £2K a year); rewiring the electrics, upgrading the plumbing; installing a new septic tank; ceilings over-boarded/skimmed/coved; new high spec DG; loads oak external doors/bifolds; oak skirtings/architraves and window boards; full 400sqm k-rend; roof sorted; almost 370sqm of porcelain tiles; as replaced all soffits/eaves etc with decorative brickwork; new kitchen; new bathrooms; £25K on garden/drive and garage; and everything replaced/restored, to very high standard.

My estate agent is now pushing me to list it for about £550K as he can't find retirement bungalow buyers who are willing to spend more. It is my view that such buyers will not want to purchase it anyway regardless of price.

I find this crazy and want to list it at a similar price to other 250-290sqm houses of similar spec/size/location, which are valued at £800K plus. He won't accept the fact that bungalow generally cost about 1/3 more to build, so therefore it should be worth more – he says this is ridiculous.

I was born into speculative building family, 60 yrs ago, spent all my childhood on-site with five years full-time in building site management, part 1 RICS, two years in estate agency and have extended and restored three previous bungalows and six houses and made profit on them all, so I understand how restorations work.

It seems like estate agents and even surveyors, struggle to understand that my market is/should be not be limited to the typical 100-150SQM retirement bungalow buyer with £400-£600K budgets.Half an acre of land with PP here is worth around £300-£350K alone.

The bungalow now is 265sqm and it's virtually a new build and gets £33k+ a year from FIT and RHI, so it only has a net total heating/power cost of about £400-£500 a year and water only £21 a month, so it is crazy cheap to live in.

This is driving me crazy. How and why is this happening?
