I am feeling the pressure to get out of paying rent and into a primary but in SD County it is so hard to get the numbers to work. 

Large pools of wanna be buyers and limited availability of existing / under building of new homes for decades keep the supply / demand imbalances in place thus keeping upward pressure on pricing.

In case you haven't heard, Congress is under pressure to raise the national debt ceiling before Oct. 18th to prevent the U.S. government from running out of money to pay its bills.

I didn't check the link and assumed they were the type that mounted into the wall and vented through the roof. 

We still need to replace the old plumbing with PEX but as of right now, we have great water pressure despite the house being over 120 years old (by the grace of God).

That’s why proper planning, doing the correct math,and developing a solid budget when going into the deal are essential.Bad or No TenantsIn the BRRRR strategy, the pressure is on to have tenants in the home before refinancing,as they want their costs covered and having the property rented is often required bylenders.

Residential lots are under the same pressure.

@Michael FureyPlumbing:Check for leaks and other signs of water damage, such as water stains on walls or ceilings.Look for rusty or corroded pipes, which can indicate that the pipes are old and in need of replacement.Check the water pressure to ensure that it is adequate.Look at the condition of the septic or sewer system to see if it needs repairs or replacement.Inspect the water heater and other appliances that use water to ensure that they are in good working condition.Electrical:Check for frayed or damaged wires, which can be a fire hazard.Look for overloaded circuits or outdated electrical panels, which may need to be upgraded.Inspect the condition of light fixtures and switches to ensure that they are in good working condition.Look for signs of wear and tear on the electrical system, such as scorched outlets or outlets that don't work properly.Confirm that there are enough outlets in each room to meet the current standard.Make sure the grounding system is present and efficient to guarantee safety against electrical hazards.It's also important to keep in mind that an old electrical or plumbing system may have to be brought up to code before you can sell the property.

I would simultaneously put pressure on the other Landlord that allowing this guy to stay is costing you money and you may decide to come after him for it.
