The purpose of a loan modification is to bring a loan contractually current and make the new payment in line w/ the new economic situation the owner is experiencing.  

What purpose do you expect the website to serve?

Let's assume for the purposes of the discussion that the existing rentals are very profitable, 100% occupied.

Resources, support, education, relationships, a sense of purpose, the opportunity to make a difference, ... most of which you can't get from "the gurus".We have a saying around the office: come for the coffee, stay for the education.

If you get the house appraised there is a statement included that the appraisal is only good for the purpose it was ordered for and can not be used for other purposes.

Well I was in the thick of it back in the day.. both as a HIGH volume real estate agent ( owned and office and had a team) and HML in the Deep south. so I think I can speak to this a little.For the CA borrowers it was all credit score driven... and just like today were you see posts I live in LA but need to invest other places.. lenders made those loans far to easy for folks who eventually lost the assets.. in the DEEP SOUTH  and I mean Mississippi can't get any more deep south than that I was the largest hard money lender in the state for many years doing 300 plus loan in Jackson a year. for fix and flippers who sold not only to investors for rental purposes ( see above almost all out of  state) to homeowners.. the issue that caused much of this is CRA never mentioned and most don't know what it is .. its the Community Reinvestment ACT that Clinton put in.. it basically forced banks if they wanted to work in certain areas they MUST provide loans for the citizens who live there...

@Karl Johnson    I am not sure what the purpose would be. 

You might defeat the purpose as your DTI would be higher after borrowing your reserves.  

Perhaps getting good at photography and offering to take pictures of for sale property for advertising purposes (for a price).

My assumption is your lease and/or state law allows you access for inspection purpose with appropriate notification.
