Variances can be a valuable tool to create value but I wouldn't place this opportunity in that category as not enough value is created to make the process a worthwhile pursuit. 

When trying to forecast the value of the property after the work is done, what tools/framework do you use?

It's all about the cost of opportunity, if you don't pay and choose not to have MLS access you can possibly be costing yourself thousands of dollars in commission because you don't have the tools to do business.

I've also used Awning but the data seems to change so I'm wondering if there is a tool that is accurate and reliable. 

I have a rental condo worth about 550 payment is 1000 per month HOA dues are 150 per month currently rented at 2000 per month just did comps through the bigger pockets tools and it is showing 3700 as a good comp for rent.  3 bed 2 bath with 2 car garage.  

Other PMS seem to do this (hospitable and host tools).  

Very kind of you to offer this tool @Liam Maher.

Remote Real Estate Transactions: With the rise of remote work, what tools and processes have you implemented to facilitate transactions from afar?

How do you plan on using that financial tool?  

Such a powerful tool when used right.
