If there is any maintenance issue, how do you deal with it?

I recommend you routinely take time to unplug, reflect, clear your mind and recharge.

The problem is that there is no road Maintenance agreement for the 200 yard long (give or take) gravel drive.  

As part of effective risk management, all firms will be required to have a documented process for onboarding, maintenance, and internal audit.

Before you start increasing rents, the equitable thing to do would be to add value to the tenants, whether it would be to take care of deferred maintenance or some other value add.You need to put yourself in your tenant's shoes.  

Taxes about $3000Insurance $3400Below are June's rent roll, maintenance & repair summary along with the YTD totals.  

Low maintenance - Concrete requires much less maintenance than wood, especially in dry and sunny regions like California. 

We have some concerns with considering expenses in our model, specifically with replacement reserves in comparison to general maintenance, how much to set aside for reserves, etc.Thank you!

I think insurance is around 220/month.I did the numbers and cash flow is around 130/month considering 10% reserved each for capex, vacancy, and maintenance.

This assumes that you set aside $150 for maintenance and 5% for vacancy, that you self manage and that your HOA fees cover the issues outside of the walls.
