So my last post seemed a little empty, here's are some add ons for you.Things you might want to try:[1] empty a room in your house and make it your dedicated office--paint or wallpaper it just like your old office--same stuff on the walls, etc...[2] Put in a desk like you had when you were working--spend the money to get what makes you feel productive.[3] Get a very comfortable desk chair you can sit in for hours a day.[4] It's COVID time, so use ZOOM to make some calls when you would normally meet in person.[5] If you're a drinker, put a mini-bar in your office so you stay put there vs going to the kitchen for a beer and getting side tracked.[6] When you're burnt out on a task, have some kind of fallback use of your time, such as reading an ebook about the business.[7] Eat breakfast everyday before going into the office and take a lunch break (if you are non-COVID afraid then go out for lunch 5 days a week).[8] Make the office your daily base of operations vs just your home.[9] Make a Vision Board on Excel.[10] If a computer CRM is not your friend--buy and use a Roldex from ebay.Just my 2 cents.

Your task now is to figure out how this is both a low risk deal and has great upside for the lender.

Assuming that you have a properly formed contract, the short answer is that they can refuse to perform, but there will be consequences.Those consequences normally play out in court, so it's not normally worth the cost to pursue it. 

Looking to scale into the multifamily arena, I began investigating services that offer opportunities to join their community and "be coached" to achieve this task more effectively.Most of these services charge upwards of $20k-$40k. 

At the end of last year, they were saying ~$700k/home and w/ the way the market has been performing, I'd be surprised if that wasn't $800k.

The rental has been performing great!

Calculating an ARV seems to be an easier task, because I can evaluate the sale prices of similar properties in the area, with respect to size, quality and location.However, estimating rehab costs is difficult.

What else do I need to do besides the tasks above?

The Negotiation Dynamic is like a stage, where the performance (your negotiation with the Seller) is about to play out.And that stage is set by your lead generation strategy.

Offer to take a lot of the menial tasks off of their plate, be their assistant, in exchange for showing you the business.
