Speaking as a Tenant...
I have known my landlord since I was 13, he is my mates dad, I have rented a property from him for the last 4 years with no problems on either side (not even a rent increase

), sure I have maybe not had enough to pay the rent maybe once in the time I have been here with my fiance but I made damn sure it was paid in full the next month.
Never had an inspection, just invited the family over for a bbq each summer and shown them around to let them see what we have done (we have a free reign to decorate as we see fit) and have never had a problem, he always says that we have to live here so we should make it as we like it.
We wanted laminate flooring downstairs, he financed it, we fitted it, after all we benefit as we get what we want and he gets the long term added value to his property.
The moral is, if you do rent out, get tenants like my fiance and I, honest people who are house proud that take a pride in our home. I do not mind spending a few quid here and there, if a tap need replacing etc I replace it as if the place was my own. Why hassle the landlord over a fiver? no need.
Some may disagree with the above but it works for us and we have bever had any problems and look forward to many more years here.
