Cash out refinance for new investment

[Nina Shell]

I am looking to do my first cash out refinance but I have a couple of questions. I don’t know the worth of the house. I had an appraisal done about five years ago but we have another bedroom to count now in terms of comps. My question is, can I get my own appraisal before refinancing and would it be valid if I did? I’d like to know my loan to value ideally before getting into the process. Also, how is the lending scene looking for cash out refinances on a rental?
