Have the tenant sign the docs and offer them 72 hours to make any additions to your move in inspection report. 

I keep a little 7.5 cu ft fridge and offer to have my handy man deliver it the same day a tenant reports a fridge out. https://www.amazon.com/RCA-RFR725-Apartment-Refrigerator-Sta...I have our appliance guy out if it's a newer appliance or I go appliance shopping if it older than 7-8 years old.If tenants want other additional compensation, I tell them that it's not my job as the landlord to protect them from every inconvenience; we will provided a compact fridge for temporary use on request and promptly schedule a repair and replacement and they should contact their renters insurance to determine if any additional benefits are available.

If it were me, I'd tell my brother than I get my downpayment back first, then we split and additional profit at sale 50/50 (presuming he matches your other expenses).

They are substantially changing other terms in the lease by asking for an additional option to renew, asking us to refund the security deposit, asking us to allow assignment without our consent, and insisting on us paying a commission amounting to almost $10K for the privilege of giving up all that.I just wanted a sanity check that this should not be all that difficult or onerous on us!

Additionally if someone is aware of good rental management local companies, let me know. 

Have tanent who paid rent for continuous 3 months ( June - sept) in 2023 but didn't pay rent for rest of the year and didn't leave the house and end up with eviction process, so for rest of 3 months of the year we didn't receive the rent.So in Schedule E form.

As a result, I received early notice he was looking to sell.

My property is 2 bed 2 bath with an additional bed in the upstairs loft.

The house recently appraised for $550,000 and we received an unsolicited offer in the $600k range a few weeks back.

There is more leg work with Section 8, so yes most Property Managers will charge for the additional work.
