Granted, the increase in equity you have will play a big factor so make sure you are calculating that correctly.  

I wrote an article on this no too long ago, you can find it here:https://www.biggerpockets.com/member-blogs/12069/85480-should-you-grant-tenants-permission-to-upgrade-unit-itemsIf he is licensed, then I think you may have a start but even then there are a few things to consider, if you have time give it a read and let me know what you think.

@Cody Malave you ever read anything on Grant Cardone?

@Grant Cardone I agree 100%.

I want a lender who can do 5-10% down, and I'd prefer one who is knowledgeable about the various down payment grant programs.

Granted, if the line is old, there may be rough corners and edges, that are more prone to snagging things, but overall, it could be that educating your tenants could be more important than lining.

Or, if you are Grant Cardone, that's a 100% response rate, because he says even no interest is interest....hahah!!

There are a lot of laws to protect multi family tenants because of the special nature of housing, whereas a commercial tenant is going to be deemed to be sophisticated and be able to hire experts to negotiate a lease so they are often not granted the same protections.Most states let the terms of the lease in a commercial or office space govern so you probably want to check with your attorney on any lease provisions to let them cancel your lease 

I know Grant Cardone does 12-15% I have seen him advertise.

However, at the age of 22, the stork dropped off my toddler sibling and soon after a judge granted me permanent legal guardian.For a long time buying a house seemed out of the question.
