Sorry to be harsh, but how could you buy a rental property without considering all the questions you are now asking?
It sounds like you bought the property hoping it would just work out. That is not a good strategy, especially when there is so much information available.
Do you know about equal housing laws, rental registration, rental inspections, etc?
If you make a mistake in one of these areas, you could be facing large fines.
Pardon my language, but you are doing this ***-backwards.
You will now be trying to get this done quickly to get the place rented and that will cost you a lot in the long run.
I can give you one very valuable piece of advice: The most important thing you can do is to make sure you screen your tenant very carefully. Almost all housing providers will tell you it's better to have a vacant property than a bad tenant.
I'm president of a local REIA and we have a group of housing providers that meet to share their knowledge. I think you should consider joining this group or a similar one in the Baltimore area.
Best of luck.
