My partner and I use SmrtPhone for communication with any Leads.

This is my first property and I am in on this with 2 partners who are effectively silent partners and I am running the rest. 

Builders often have an escalation clause built in that says something to the effect of “if material costs increase more than 10% during the time of construction, builder can raise the price to cover the difference”. 

They cut communication off with the Landlord.

I was meticulous in communicating with the title company and buyers' agent to a successful close.

Doesnt he provide his social when he opens up water account on his name which may effect his credit history or he's the type that dont care? 

How will this effect resale value?

Has anyone been successful with communicating with a lender to post pone a sale in order to get title work in?

A main question in this kind of situation is who brought the buyer.For example, if it could be shown that the buyer came to the seller because of the marketing efforts of the listing agent, that would likely have an effect on whether or not the listing agent was due all or part of a commission.In this case the buyer is the tenant and therefore wasn't brought to the transaction via the listing agent (unless the listing agent procured them as a tenant in the first place, in which case I don't know if that would count), and the listing agent apparently hasn't spent any money on the listing yet.

I like your idea of communicating the list of changes I plan to make to the tenants to help justify the increase in rent.
