On 4 it is $12,000/year.  3.3% depreciation is similar numbers - usually almost eliminating all your taxable income from financed properties after repairs and maintenance is factored in. 

Look for any maintenance issues that tenant perhaps failed to report.

I was told it was done just for preventative maintenance early on as the area had had some settling issues in the past with other properties.

Maintenance costs to 5%?

And, to-boot on LWO I could actually press any property maintenance onto seller.

I put some numbers below into this Rent or Sell calculator.https://www.narpm.org/members/resources/rent-vs-sell-calculator/ESTIMATES ON ROI (15 year time frame)at 5% Appreciation would profit $100K if SELL nowat 6% Appreciation would have $3,500K more if KEEP and sell after 15 yearsat 7% Appreciation would profit 122K if KEEP and sell after 15 years(Assuming a conservative 6% ROI on money invested from sale.)NOTE: The property appreciated 10% in the last year so I’m thinking 7% over the next 10-15 is reasonable.DETAILSSale Value: $520,000 (Best guess)Paid: $437,000Original Mortgage: $415,000Mortgage Balance: $380,000Interest: 3.375%Monthly mortgage: $2,899Mortgage Difference: $1064Annual Taxes, Insurance, HOA etc**: $20,345**$13,865 (Non Homestead tax) $4,680 (HOA) $1,800 (Landlord Insurance)Monthly Rental Charge $3,500*Appreciation 7%Years to Hold: 15More assumptions used in ROI Estimates Above90% occupancy,15% capital gains charge6% selling feeRate of return on gains if selling now instead 6%Annual maintenance 1%Annual rent increase 4%$3,500 is slightly aggressive. unlikely I could get more.Thanks in advance for any constructive thoughts and comments!!!!

Note owner occupied does not have vacancy, unit turnover costs, and typically has lower maintenance and cap ex costs.

Newby investor doesn’t factor in maintenance, capex, turn over costs, vacancy costs the same as another investor.  

I utilized 7% for CAPEX and 7 % for maintenance given recent updates .Tenant pay for electricity and gas.

if you haven't already, do a Capital Expense/Deferred Maintenance analysis of all six properties.
