Let's un-muddy the waters...First, income from trading, like investment income, is not earned income for retirement account purposes. 

The first invoice was on 9/30/2020 and had a description of "home owner was getting water hammer from hall bath stool. 

The hoa also pays for water service because the entire complex is metered as one (which also sucks, btw).

I'm also concerned because in my counties, the water utility  will never be shut off, it simply rolls over to the property owner if unpaid by the tenant.   

BUT get used to having the accounting deal with that 10%.Expenses: Mortgage Rate 3.00% Length of Mortgage in years 30 Monthly Mortgage payment $632.41 Taxes $ 150.00 Sewer and Water $ - Trash $ - Heat/Utilities $ - HOA/Legal $ 8.50 Cap Ex and Ops $ 250.00 Insurance $ 100.00 Mgmt Fee $ 160.00 Vacancy $ 132.80 Total Expenses $1,433.71

Yes, swim, water ski, walking up the hill from the dock to the house.

Bathroom hardward (TP and towel racks) - mount to a 1x4 plaque that is screwed to studs. you can pretty much hang on it without pulling out the hardware. i use entry level granite countertops - stain resistant, and should last a long time. i put LVP through the entire house, bathrooms and closets included. its water proof and scratch resistant. while the initial cost is more than carpet, you wont have to replace it as often. i use Sherwin-Williams Harmony line of paint, in a semi-gloss sheen. the semi-gloss is easier to wipe off for small marks, and the harmony line has deodorizers built in. for exterior door knobs, i use the smartkey knobs from kwikset. you can rekey a knob in a few minutes - no need to pay rekeying fees anymore. last tip - figure out which appliances your market typically provides. in my market, its not common to provide washers and dryers, so i dont. thats one less thing to have to repair. 4. i dont see an issue with the gas stove. to convert to electric you will need to have a 220V plug, which could be costly to install if not already there. 

Here's an excerpt from the clause in the lease (you should check for a similar clause in your lease so you know what it actually says):INSURANCE: Tenant’s or guest’s personal property and vehicles are not insured by Landlord, manager or, if applicable, HOA,against loss or damage due to fire, theft, vandalism, rain, water, criminal or negligent acts of others, or any other cause.

The water pipe in the yard had busted and was gushing for 2 days.- Vacancy insurance for homes you are holding Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

You can purchase lists with different motivations like absentee owners, 60-90-120 days late on mortgage, pre-foreclosure, delinquent taxes, water cutoff, code violation, evictions, probate, divorce, etc. and mail or cold call.
