@John Thedford There is no need to threaten and abuse the OP.

Obviously questions about religion, sexual preference etc. are irrelevant to a landlord and will not come up. 

This is sometime used and abused by tenant. 

If it weren’t for the moderators, the forums would be overrun by solicitations, abusive remarks, and it would dilute the value of the content and drive the good contributors out and attract unwelcome posters.

Be nice and ask him to call his insurance, if he becomes angry or abusive walk away, or tell him to pound salt.

I went in and used (abused?)

(A) A landlord who is a party to a rental agreement shall do all of the following:(1) Comply with the requirements of all applicable building, housing, health, and safety codes that materially affect health and safety;(2) Make all repairs and do whatever is reasonably necessary to put and keep the premises in a fit and habitable condition;(3) Keep all common areas of the premises in a safe and sanitary condition;(4) Maintain in good and safe working order and condition all electrical, plumbing, sanitary, heating, ventilating, and air conditioning fixtures and appliances, and elevators, supplied or required to be supplied by the landlord;(5) When the landlord is a party to any rental agreements that cover four or more dwelling units in the same structure, provide and maintain appropriate receptacles for the removal of ashes, garbage, rubbish, and other waste incidental to the occupancy of a dwelling unit, and arrange for their removal;(6) Supply running water, reasonable amounts of hot water, and reasonable heat at all times, except where the building that includes the dwelling unit is not required by law to be equipped for that purpose, or the dwelling unit is so constructed that heat or hot water is generated by an installation within the exclusive control of the tenant and supplied by a direct public utility connection;(7) Not abuse the right of access conferred by division (B) of section 5321.05 of the Revised Code;(8) Except in the case of emergency or if it is impracticable to do so, give the tenant reasonable notice of the landlord's intent to enter and enter only at reasonable times.

I would avoid time and materials when ever possible, to much room for abuse.

Rental deposits are really the tenant's money that is held by the landlord against damages you may suffer (when the tenant vacates) due to damage due to tenant abuse, unpaid rent, and even for a broken lease.

The work turnkey has been used and abused but simply stated all major components have been replaced, the home has been renovated to 2020 standards esthetically and to code, and will attract a highly qualified tenant.
