You will certainly be over loaded with different information and worries when you are about to rent a house or an apartment. You will be consumed into finding the right location, with an affordable price, good neighborhood and many other worries. Similarly landlords have their proportion of such worries as well. Yes they have the property, but what they are looking for are good tenants who could take care of this property responsibly.
If you want to be guaranteed about the interior of the house, its safety and security, you can always ask them for a pre purchase house inspection. This does not make you look too picky or demanding but it shows that you are indeed interested and careful about your choices. This can help you look responsible to them as well which exactly what they are looking for.
It might be common stereotype for the landlord and the tenant to have a stern relationship. This does not have to be the actual reality for many and can actually be worked on from the very beginning itself. From the point of a tenant, you may feel like you need to be stern with them because of your prejudice against them consciously or not. Release yourself from these stigmas and being polite to them from the very beginning can actually pay off. One of the main things they want you to be punctual about is the monthly payments. Make sure you pay on time and if you are facing difficulties let them know beforehand.
As they are informing you about any casualties of the house or simply telling you about how certain things need to be done. Listen to them. They are telling you these things for a reason, you may at that moment feel like you are already aware of these things but when you come to actually try them it might be the opposite. This is because not every home has the same structure and ways of doing things and listening to them can vastly help you in situations. Be careful of the things you do, pipes or a certain part of your home may become damaged. However before you do call them to complain, be sure of your actions, and question yourself about whether this happened due to your own doings. After that call them and place your complains, no harm in it but try to be polite.
The house that you are now living in was the house of your landlord in the very first place. Think about the reasons why they may have decided to lease it in the very first place. It is after all, their home and would be precious to them much more than it will ever be to you. Such thinking can help you further take care of the property well. Let them know if anything happens, do not fear over how they might get angry or disappointed.
