Once you have worked with a landlord one time (if you did a good job for them) you could get called back over and over again.
They may even recommend you to other landlords.
One thing that is different with landlords is that you can get paid as you are done with the work. You do not have to wait the 30 days or more, as you have to do with the property preservation.
They have need of things being hauled away, cleaned up and fixed up.
If you know how to do repairs and fix up you can get a lot of work from them. This can add to your bottom line.
We have worked with a few landlords. They pay well and if they want your help in the future they will pay you when you are done.
Can you find ways to help them save money by cleaning up something instead of replacing it. That helps them out as well and they will come back to you with more work in the future.
Get to know some landlords with a lot of properties and you could do that regularly. If you have collages close by that is a good way to get a lot of move in's and out regularly.
Have fun expanding your income with the landlords in you area.
