ᐅ Semi-detached House Renovation (Built in 1999) Cost Estimate

Hello everyone,

I have the following offer:
Semi-detached house, built in 1999, solid construction
With a basement and a living area of 140m² (1,507 sq ft)
Double-glazed uPVC insulated glass windows
Energy certificate E141.1
Solid construction method
Oil condensing boiler, wood stove
Underfloor heating in the living/dining area, radiators upstairs

From my perspective, the following work would be necessary:
- Renovate bathroom and guest WC
- New floor coverings upstairs (currently cork flooring)
- Re-tape the walls on ground and upper floors
- Exterior facade repainting
- Heating system from 1999, still has about 9 years lifespan before renovation, so not immediately necessary

Own work: Remove and install floor coverings, strip and re-tape walls, gut bathroom and guest WC

What financial effort can be estimated here (standard/normal fittings)? Or, what should the property cost so that the renovation of this scope makes financial sense?

That depends. For example, what materials do you plan to use? What exactly do you mean by renovating the bathrooms? It won’t be expensive – but that is relative (it’s only a minor cosmetic update, not a major renovation).
What should the property cost for it to be worthwhile? In Munich, with a good location and a large plot, probably no more than 1.5 million. Near the Polish border, rather around 150,000. So how are we supposed to know? Are there enough alternatives available to you?

Regarding bathroom renovation:
Remove old tiles and install new ones, possibly vinyl depending on which is more cost-effective.
Replace the bathtub and shower.
Install new double sinks and a toilet.
What would qualify as a comprehensive renovation?

The estimated cost before renovation is 390,000 (area around Ulm). There are limited options available in this region.

Is an oil heating system from this construction year still suitable for renovation, so it can be used in the future? Or should one switch to a different technology at this point?

If you want a new oil heating system, do it NOW. In a few years, such systems will very likely be prohibited.

Costs vary greatly depending on personal taste. If you remove the old tiles yourself, expect around 7000 Euro (about 7,700 USD) for a bathroom with basic fixtures and mid-range tiles up to 60cm x 60cm (24 inches x 24 inches) in size.

If the heating system is to be upgraded, it will most likely be oil or gas again, since an older underfloor heating system and radiators are not ideal for a heat pump. Does the house have a gas connection or is gas available on the street?

New oil boilers are very efficient nowadays; if I were to switch, I would do it right away, as Scout mentioned. However, it doesn’t hurt to check with the utility provider whether gas is available on your street.

390,000 sounds realistic for Bavaria at first glance... and in a well-maintained house built in 1999, you don’t have to take immediate action. But you really need to start setting money aside now for the expenses that will definitely come up eventually.
