Leasehold, whats better - flat/apartment in a block, or coverted house?

[justwhy2022]

As the title asks...

In the process of buying a flat in a block. But reading the Management stuff is a little scary. Wondering if it would be better going for a flat in a converted house, where you may have just 1 above or below you?

No point telling me not to go leasehold, its all I can afford.

My gut is telling me i'm doing the wrong thing by going for a block and that is because of the service charges. I know you can have service charges and ground rent in a converted house as well, but my feeling is that there may not be any 'surprise' costs as much, such as the roof needing redoing and you all having to pay towards costs of £30,000 for example.

Am I right to assume this or wrong?

Isn't it all about control? If you and your neighbours own the freehold then you control the sc, whether it's a house or a block.
You also want to know how much has been saved already for these big costs. If the roof is going to cost £30,000 but there is £100,000 in the Reserve Fund then it's not a problem.

The question is not block or house. It's (a) who owns the freehold (b) what are the terms of the lease (c) what is the condition of the building (d) is there a Reserve Fund.
