Stop torturing yourself. Hire a property manager. The small commission paid is much more advantageous than you can imagine. It will save your sanity and make your business flourish.
The reason people hate being a landlord is they are personally involved in their tenants "world". Don't be. This is a business, tenants are the income stream. Make sure the MANAGER knows how to say no and you won't have to. Forget about your perceived "lose of control". If the property manager is good (get referrals) then you will spend your time doing property deals which is where the real money is. You will end up making more money with a manager in place after a short while. Why?
Without tenants, toilets, and trauma you're only spending your time looking for and doing deals. You will be so much happier. If the property is a break even or positive cash flow with the manager in place, do it! If the property can not support a manager (it's probably not a good investment property) and you insist on keeping it you should...
Put the title in a trust or LLC (or change your existing Trust or LLC on title to a new one). Then send a very very short business (non-personal) letter to the tenant (DO NOT CALL THE TENANT) that says:
Dear Tenants at (the address):
The (home, apartment, condo, etc at address) is now owned and managed by (Name of Trust or Name of LLC). Please make all rent payments to (name of Trust or LLC). A representative of the the trust (or LLC) will be your contact and will reach out to you shortly with additional information. Please do not contact the former owner, they will simply refer you back to the new management. Thank you.
Sincerely,
(Name of new Trust or LLC) * do NOT put your name here!
Then, do not answer the tenants calls (use caller ID). Do not call or write to the tenant yourself. If the tenant gets through to you somehow, just say "I'm sorry, I'm not the owner anymore (name of trust or llc) is". Please contact the new management. There number is....". Then,
Get a PO box and have the trust or llc tell the tenants to mail rent checks to the trust or llc. Get an answering service (cheap). Let the service answer take all tenant calls on a specific number (NOT YOUR OWN NUMBER). Have them answer calls "Hello (this is Name of trust or llc". Have them take all tenant's messages. Then the service gives you the message. Do not let the service give out your name or number, NEVER. You can even use a cheap recorded voice mail service (do not use your number) that records tenants messages (no live operator). You retrieve the messages. You will delegate all repairs to a handyman or someone of your choice. DO NOT do repairs yourself even if it costs a few extra bucks. Make sure the repair person NEVER mentions your name to the tenant and refers only to the (trust or LLC). And,
Find a realtor (anyone but yourself) cut a deal. Pay them a small fixed amount per conversation (it's easy money) with the tenant. Hire a "hungry" realtor to be the voice of the trust or llc. The realtor never mentions your name just the trust or llc. Do not do a standard management deal with the realtor. You will give info to the realtor, they relay the info to the tenant. They are the mouthpiece for the trust, llc. The realtor tells the tenant to always call the management service (answering service number) first for all needs (not the realtor).
If you need to deliver a late notice, notice of eviction, etc, let the realtor sign them for the trust. If you ever need to evict, NEVER do it yourself. Have an attorney specializing in evictions do it for the trust or llc. None of this is expensive. And will save your sanity. But honestly,
If the property does not cash flow enough to have a property manager do all this, get a different property. The beauty of doing that: It can be a cheaper property in a lesser area (drop your ego). Why? Because it will cash flow better and using a property manager you never have to deal with the tenants.
Good luck!
