As the deal size gets larger, this should get lower. 

There are larger databases (Co-Star) that have information on larger properties, but I'm personally interested in small to mid-sized multifamily.  

I think the top factors are type of home (comparing single family to apartment is no longer done), overall size, and interior features like central AC, approximate age of renovation, etc.

There have been some famous scientific studies that showed people were far more likely to want someone else knocked down to size than for themselves to be lifted higher if they perceived a situation was unfair.

The home buying process typically follows these key steps:Assess Your Finances: Review your credit score, savings, and determine how much you can afford for a down payment and monthly mortgage payments.Get Pre-Approved for a Loan: Work with a lender to get pre-approved, which gives you a clear budget and shows sellers you’re a serious buyer.Find a Real Estate Agent: Partner with an experienced agent who knows the local market and can guide you through the process.Search for Homes: Browse listings and visit properties that fit your criteria (location, size, price, etc.).Make an Offer: When you find a home you like, submit an offer through your agent, including contingencies (financing, inspections, etc.).Home Inspection & Appraisal: Once the offer is accepted, hire an inspector to ensure the home’s condition and the lender will order an appraisal to verify the property’s value.Secure Financing: Finalize your mortgage by submitting required documents and ensuring the lender clears you for closing.Closing: Sign the final paperwork, pay closing costs, and receive the keys to your new home!

One size does not fit all. 

Now the rents have skyrocketed over the past year and we find we could be renting to a regular sized family for about $200 less than what we get now!

For starters it can be more difficult to find comps as there are often less multi fam trading than SFR of the same size and count.

Depending on the size of the discount when the note was purchased, this often resulted in a 5- - 100% increase in ROI. 

I just sent them a larger list with a bigger size to test again and if it returns as bad as the first time, I'd be looking for a new company.
