Otherwise, yes you have to either excavate and repair and replace or run a pipe burst through the line, which is usually as expensive as excavating. 

@Jack Cottrell You Vacancy & Maintenance percentage are aggressive and may only work for a Class A rental/tenant.If the is a Class B or C rental that will attract Class B or C tenants, you should strongly consider increasing those percentages.NOTE: we deal with a LOT of Class B & C rentals, so we replace "Vacancy" with "Vacancy/Tenant Nonperformance".

It’s easy to switch it up or add to it or replace it if parts or the whole thing gets damaged.

Labor/material are going to be different and need to factor that in4) new roof, new HVAC, new water heater, ac panel, replacing plumbing to PVCThese are very variable, if you are getting this from a licensed guy to do it and unlicensed.. is it a big shop or a local shop doing it, is the GC doing it they will put some money on the top so it will be more money5) framing (creating new bedrooms or baths)I would get all these quoted from a good couple of licensed guys and unlicensed to know your numbers to cents

They expect us to replace lightbulbs, won't change furnace filters and we also have lawn maintenance issues with them.

I recommend establishing a reserve fund for major turnover expenses, capital repairs like a roof replacement, etc.

I require tenants to replace consumables like refrigerator filters or HVAC filters.

Be ware of the ones that get compensated on the back end by trying to refer you to replacement property solutions that compensate them.  

We hope that you can remedy the situation so that we can move into a habitable home.Suggestions that we have to fix the issues:Hire a company to rip up the carpets, treat the subfloors, and replace the carpets, at least on the main level and on the stairs.Provide an air purifier as a start to remedying the smell.Replace the garbage disposal.Hire a plumber to fix the draining issue in the bathroom sink of the smaller bedroom.Fix the tiles in the upstairs bathroom so they no longer present a safety hazard.Replace or fix the screen doors.Fix the gap between the windows and the walls in the living room.Hire a professional company to treat the entire home for pests.

If it’s an older property or has deferred maintenance, you might want to lean toward the higher end.When it comes to CapEx (capital expenditures), planning for major replacements like roofs, HVAC systems, and appliances is key.
