Ideally, looking for 'standard' contracting for the state that is aligned with local / municipal /state laws pertaining to tenant and landlord regulations.Thank you.

Property tax, occupancy tax, personal property tax, business tax, permit/inspection fees, higher than standard utility fees, ever-increasing fees by the platforms.  

Plan on 1800-2900 for standard rental home. 

Maybe 5% would be my threshold but still would take putting lots of cash at risk for pretty moderate returns (by real estate standards).

I had one particular vendor with high standards that would exaggerate anything he found.My rule of thumb: people can live how they want to live as long as they are not 1. damaging the property2. living in filth that attracts pests3. impacting the neighbors (e.g. odors, junk detracting from the neighborhood, etc)4. creating an unsafe situation (e.g. hoarding and rescue workers can't access the home)When I visit a property, I document any issues and talk to the tenant.

Although rents increased by 2% annually, the purchasing power of this income is equivalent to $4,325 in today's dollars.Year 10: $5,000 x (1 + 2%)^10 / (1 + 5%)^10 ≈ $3,742Year 15: $5,000 x (1 + 2%)^15 / (1 + 5%)^15 ≈ $3,237Year 20: $5,000 x (1 + 2%)^20 / (1 + 5%)^20 ≈ $2,800Due to rent increases failing to keep pace with inflation, you won't be able to maintain your standard of living.

Now I've finally hit a much more steady patch (knock on wood) now that they're all renovated and up to a certain standard (new roofs, hvac, etc).

A qualified professional appraiser will generate a comprehensive analysis considering factors such as sales comparisons, highest and best use, market conditions, and income generated following Uniform Standards of Professional Appraisal Practice guidelines.

What I did to combat this was make the review standard clear to guests in all your messages to them.

I fired my property manger in 2 months after they did not perform to my standards.
