The time period under consideration is also a key ingredient: your above post seems to implicitly assume an annual period - this is both a common and convenient window, but other durations may also be used.If a landlord choses not increase rent on a tenant at every opportunity that presents in the short term, it does not preclude an optimized performance of the property over the longer term.We have an instance right now where we have chosen not to charge market rent.  

That's why if I had good reason to suspect trouble brewing, it would be one approach worth trying.When we do periodic inspections (at least twice a year) and enter the residence, not only do we give our tenants legal notice to enter, but we ask them for a date and time that is convenient for them and set an appointment.

I am looking for a convenient and inexpensive way to collect rent online, if you have any suggestions of other online services.

I think you just need to be realistic that it doesn't make sense financially, but you just want to do it.I choose to rent right now at this point in my life because I like the convenience of it.  

I think you'd be best off getting something that would wear better than the super cheap stuff.As a tenant, I just want outlets and switches that work, and preferably a lot of them in convenient places.  

I have them schedule directly with my calendar so it's convenient with them.

I don't think they are particularly unreasonable for a careful landlord, but I think the quality of tenants in the area might not be so great to begin with and including these details upfront makes me come across as a tough landlord:  Application: Background check ($25) Past landlord, employer, and personal referencesLease Points: Initial lease term is 8 monthsMonthly rent of $865 due on the 1st of each monthRefundable Security Deposit of $865Pet Fee (if applicable) of $200 upfront and additional $25 per monthOptional FrontPoint security system for $100 upfront and additional $50 per monthTenant pays for water, gas, and electricityRefrigerator and range oven includedWasher, dryer, dishwasher, and microwave not includedNo smokingAbsolutely no illicit drugs or other illegal activityTenant responsible for damages beyond ordinary wear and tearTenant required to purchase renter’s insurance before move-inNo assigning or subletting without landlord’s permission* The above list is intended only for purposes of convenience and is in no way incorporated into or comprehensive of the Lease Agreement, nor is it binding.

You cannot just put in whatever rules you want to suit your convenience.

They also help 'sell' the place to the potential new tenant, talking about the lifestyle or conveniences that comes with the house, and it seems to help minimize the vacancy period.Does anyone else do this?

I've had some work done but leaving so much money on the table is ridiculous while they pocket the savings because it's "convenient" for me to keep the same tenants.
