@Charlesa F.Your realtor and attorney (if you are using one) gave you bad advice. 

If you don't want the partnership at all, then you should ask your brother if he is okay with that and instead maybe you give him a market rent or even a few hundred below market for a year or two as a "my bad, I didn't think his through but I still love ya."

I'll second @Jonathan Greene , @Michael Smythe , and @Michael Paling - BRRRR and flipping are bad ideas when you don't have any money or experience.

This example would yield a pre-tax net of $340/month (minus any vacancy credit or capital set aside for maintenance (capex).

Tenants sometimes thinking they are trying to act in their best interest, can bad mouth a property and scare some buyers away.

I know a lot of people use Avail but consulting with a local real estate attorney is never a bad idea.

I would suggest taking out what's called a home equity line of credit and use it to invest in more real estate but make sure that you have a mentor that has done at least 100 times what you are planning to do and follow a strategy that works for you.

For my small size it seemed unnecessary and I didn't see the benefit in the small companies for a small time guy like myself.What I do is I can collect rent through Venmo (free), I have a tennant application embedded into my website (cognito forms...also free) I screen tennants through mysmartmove.com (Transunion's company gives you credit report, background, criminal, eviction etc. and tennant pays for the screening so also free.) 

I also have a partner with a full time job and great credit score as well, so maybe my best option would be to include him and have him apply for the mortgage.

The houses are warranted and easy to rent, no repairs will be needed in a while, sometimes the builder credits are good, plus they enjoy the appreciation that you receive from buying early in a community.
