Noobie Question(s). Number of rooms?

[Daniel L.]

Planning on renting out my current primary residence in a couple months. It's a 3 bedroom 2 bath. One of the bedrooms had a portion of the wall opened up into the dining room. 

Do you think this will effect getting a tenant?  Do you think it would be worth having someone close up the wall before putting it on the market to rent?

If you were to close this wall of how do you go about finding a good contractor(s)?  Would you find a general contractor or is there a better way to go about such a project?

Thanks,

Dan
