Hello! I would like to briefly introduce myself and my project and look forward to a productive exchange!

I am 42 years old and have inherited a house in a suburb. The house has been vacant for about 10 years. It was built in 1973, has approximately 105 sqm (1130 sq ft) of living space, and a small garden. I have already brought it back to a “shell condition” myself. However, my DIY skills and available time outside of work for further own work are unfortunately quite limited.

The house is fully basemented, but the basement is quite damp. There is one more floor with sloping ceilings. The attic is not usable or accessible due to these slopes. The house has never been renovated since construction and is in a correspondingly poor condition. All windows have roller shutter boxes without insulation. The walls are not insulated, and the roof hardly is either. The roof itself also needs renovation. There is an old oil heating system and no gas connection.
There is no gas connection available on the street either.
The building’s core is in good condition (no damages).

I have consulted an energy advisor who recommends renovation to an energy standard equivalent to KfW House 85.
The scope of work includes insulating the basement ceiling, roof, and exterior walls; new windows; a new roof; pellet heating with solar thermal, and possibly photovoltaic (south-facing roof 40°, approx. 80 sqm (860 sq ft) area).
He based his calculations on an energy cost of about 2700 euros per year. According to this, the renovation costs he calculated should be amortized within about 20 years. The renovation costs are “only” 48,000 euros.

Currently, I would receive 120,000 euros from KfW at 0.75% interest plus 33,000–36,000 euros repayment subsidy, as well as up to 30,000 euros in subsidies from BAFA for the new heating system.

With a contractor, the preliminary (verbal) quote for the complete renovation is around 180,000 euros, which also includes bathrooms, windows, flooring, etc.

What are your thoughts? Do you have any comments – things I might be overlooking?
I am somewhat uncertain about the pellet heating as the contractor has never installed one but seemed confident that it can be done properly.
The location is ideal for me regarding family and work, so it is very important for me to be able to settle here.

Best regards!

What do you think about this?

Well, getting a fully renovated house for €180,000 (approx. $195,000) compares to either buying land and building new. Financially, new construction would already be at a significant disadvantage—excluding the location that suits you best.

I’m not a fan of pellet heating; I would prefer a “standard” air-to-water heat pump. Maybe even a Geisha system for a very low cost.

However, €180,000 (approx. $195,000) seems expensive for 105 square meters (1,130 square feet) of living space (including photovoltaics?). That’s €1,700 per square meter (about $160 per square foot), a good profit margin for the builder. If we accept the estimate for the energy-related upgrades at €48,000 (insulation, windows, roof, heating), that leaves €132,000 for cosmetic renovations—so floors, doors, walls, plumbing, and electrical systems. Either you’re getting gold plates on the floors, gemstone door handles, or the builder is buying a new Porsche this year...

I started a thread myself on the topic of pellet heating; try searching here for my name and pellet. I believe it is not practical for most people in everyday use.

That would be a heat pump, right? I have also considered it – but I keep reading about insufficient heating capacity or high electricity costs. Would such a pump be a viable option for a house that is insulated in the future (but, of course, not like a new build)?

This is not an alternative; this is the standard. Pellets are the exception.
