I am starting with a small budget(100k-120k) so trying to understand which neighborhoods I should focus on, would love to get recommendations if you have :) I live south of the city and only like to go about 30 minutes away from home. 

But I highly recommend reading "Who Not How".

Recommend that she contact the state's rental assistance program, the victims' assistance program, and make other arrangements to pay or vacation within three days to find more suitable housing - like Section 8.Run your business - or risk having the tenant ruin it.

Or recommend any builders?

Financing might be a challenge.I would recommend consulting with a attorney, loan officer, and CPA to discuss your specific situation and determine the best course of action. 

I always recommend checking out reviews as well. 

I would recommend starting with them to get grounded if you haven't already. 

I would recommend that they invest in an inexpensive 'white noise' machine to help muffle the sound but that no property is completely sound proof and the upstairs tenants are well-aware of their concerns and are respectful.Always 'entertaining,' huh?

I HIGHLY recommend them. 

Based on the information that you shared, if you haven’t already done so, I recommend connecting with a local expert.
