I don't think you would need to worry about sub leasing if you're leasing the residence to tenants especially family. 

Why do this instead of separate leases?

Always verify any rent estimates with actual leased comps, not just what a PM says is “possible.”What is one thing you would have done differently on your first BRRRR?

Just set up the lease and get a long term tenant.

There are many posts on BiggerPockets about landlord software, but here’s a consolidated overview.Must-have features landlords mention most often: online payments, full accounting, 1099 tracking and e-filing, tenant portal, owner portal (if you manage for others), work order tracking, vacancy syndication, online leases, and tenant screening.

Communication and transparency are absolutely key, but since those are yours, I'll go with expertise in the landlord/tenant laws of the state, especially lease details and evictions.Note: This information is for educational and informational purposes only and does not constitute legal, tax, financial, or investment advice.

Buy an undervalued conventional construction house (appreciation will be much more), renovate to rental quality, sign a lease, and scale from there getting all the benefits real estate can provide. 

Some strategies I’m exploring: Seller carry / second position notes Preferred equity / mezz debt layers Master leases to guarantee income floor Using entitlements or land value (25 acres attached) to sweeten the financing package Rent bumps modeled into refinance termsI’ve seen other capital groups putting 5-10% down on $60M+ acquisitions and making the numbers work.

Not the end of the world but moving is already stressful and that just made it even more so.Also, put everything you want the tenant to do in the lease.
