Luckily my customers were pretty loyal to me but you get the point. 

If you're getting a lot of traction with prospective but qualified tenants that would like to view the unit - let them know the time that the leasing/showing agent will be there so they can view the interior.If they're going to lease the property for you - one to half a months rent is fair compensation.

We have a lot of customers at the moment who are strongly considering lifting their homes.

That's great that the bank who currently holds the note wants you on 20 year or 15 year amortization, they view you as a captive customer, they don't have to earn your business any more, as far as they are concerned. 

Many prospective buyers don’t want to pay large mortgage payments on a home listed at market value and they know enough about home renovations that they can rehab it themselves and have exactly what they want in a home and can have a small payment on it if it is purchased this way. 

As others have mentioned ...there were about 200 "prospective students the first day. 

Crypto is reaching a feverish level and they need new customers to feed the frenzy.

And the only "client" reviews I've seen mention that their customer service is non responsive and difficult to get a hold of once you're purchased their services.

I, like you run my firs duplex with the same culture of focusing on customer service.

I understand that some prospective buyers have gotten under contract but later backed out.
