What are some of the benefits I will miss out by paying cash as a 1st time homebuyer?

[Peter Chan]

I will need to find a small place for myself and rent out additional room if necessary. 

Taking out a mortgage may not be easy since I don't currently have a 9-5 job. Plus, the mortgage rate is still high and I am not kin to pay the high interest either. 

I understand there are benefits to a 1st time homebuyers but it seems like most are related to down payment assistance. Is there other benefits I will miss out as a 1st time homebuyer if paying all cash? Plan to purchase in northern Virginia or Maryland. Thanks.
