Additionally, your brother would inherit your cost basis in the property, which could result in significant capital gains tax if he sells the property later.

You will likely need to rehab for any strategy but Co-Living will be more bedroom additions which is less cost compared to kitchen and bath remodels that are more needed for furnished rentals. 

These are professionals with additional training and a stricter code of ethics.

Am I getting greedy to ask for an additional seller credit at closing to help offset some of repairs needed?

Making additional payments or taking a shorter term are just depositing more into that savings account (it's not like the property appreciates more by paying down the loan). 

Would love any additional info and the chance to check it out! 

With the economy of scale in multifamily, each additional unit nets you a little more than the last, as a rule of thumb.

Then if I have additional concerns I call in an expert to get further information and an estimate on what the repair will cost.

I’d appreciate any additional suggestions you might have! 

Given my lack of experience in accurately assessing the additional costs and potential risks of investing in an AE zone, I felt it was best to step back and refine my evaluation process before taking on something like this.Thanks again for your input!
