Hi
I agree with nicko's comment…..
Create a relation ship with your tradesmen, they are people, pay them on time show them respect and they will look after you.( maybe a beer or 2 wouldn't hurt either ) And they can become a very important member of your investing team

Form relationships with tradies as when required as they become useful member of your team and I would consider the bigger picture when you have accumulated wealth say in 10 years time. If can get by without undertaking expensive repairs can also be an viable option. You need to consider minimizing expenses. If the tenant is not asking for anything leave it alone!
