And if you haven’t performed a cost seg study before and intend on improving your property, I highly recommend doing so beforehand.ARE THERE ADDITIONAL BENEFITS TO A COST SEGREGATION STUDY?

Highly unlikely .  

Los Angeles's own numbers show that ADUs are not being built in high rent locations.

They make setting high rental prices very tough.

I would like to know the prons and cons of paying off the mortgage faster to be honest i do hate the fact that my mortgage rate is high almost 7%.  

I don't like it I have to be honest - I think part of the reason you're cashflowing is the low interest rate and relatively high downpayment.

Quote from @Torianne Baley: Hi George,Do you mind sharing the lender you found who accepts the 500 credit score and will loan $300k There are lenders out there but the risk is very high so your rate will be 13-15% plus the loan to value will most likely need to be less than 60% (or even 50%).

I could go on and on, but suffice to say the devil is in the detail, not in the high level split.

The only thing that I can think of is that the rent price could possibly be too high. 

Given Asheville’s high prices, leveraging your brother’s rent is a smart move.
