I've done some pretty good deals off of it, but they were all "Land Subdividing" deals in which other potential buyers hadn't realised the potential.

Assuming of course you are operating your investment as a business.Hobby landlords would probably wait a while then start begging for payment and eventually be forced to start the notification when they finally realise a tenant paying late is abusing their landlord tenant relationship. 

There is no way you will ever realise positive cash flow from this property.A rental property that can not show positive cash flow with a hypothetical 100% financing/50% expenses will only get worse as equity grows.

We don't have the stress of looking for another property and getting it rented.Cons:The continued stress of renting out an apartment that was finished to a significantly high standard (Quartz, wood floors etc.) as it was never intended to be a rental when I lived in it.We receive a relatively weak return on investment, especially with inflation rising.2 - Sell the London rental apartment and build a rental apartment on our landWe could sell the apartment in June 2022 at the end of the current mortgage term and use the proceeds to build a rental property on the empty land on our current home.Pros:We own the land already, so we should realise a larger yield on our investment as we just need to pay for the building of the house and associated fees.

I work for one of swedens Credit market company/ banks in Sweden as a credit officer which made me realise that i do not want to chase the everyday 9-5 rat race anymore after seeing all my customers doing the investments. 

I even thought about using this as a rental in a different forum but quickly realised it was better to sell.

I realise now that, that's a limiting belief.

I didn't include it when I responded above as I thought it was obvious, but after reading your post I realised that shimming the cabinets (if they do not have adjustable feet) is probably not at all obvious to someone who has not installed floors and cabinets before.Another approach we will do in older houses where floors may belly as they move away from {load bearing} walls is to put a ledger/cleat along the wall and sit/hang the back of the cabinets on this lip.

Hopefully Investors can look at this post and realise that a lot of questions are needed when talking to their Lawyers and Accountants.

This setup allows you to repatriate retained earnings when it is advantageous - when the CAD is weak to the USD - but not have to realise them into your personal income at that time.As you might imaging there is also a downside to a more complicated holding structure - you will have annual business registration/licence fees; tax returns to file in two countries; and more stringent bookkeeping requirements.
