Your the person who wants to sell and pre-qualifying your prospective buyers and yourself is really not a sound approach.

If it takes you $8-10k to renovate a unit, not including cost and time to find a new qualified tenant etc. a $50 -$100 a month difference in rent for a known / stable tenant in my opinion outweighs the the full turn prospect.  

It all depends on where you qualify. 

@Ricardo Polanco barely qualifies as a lease:(This "lease" leaves you open for a lot of abuse and we don't suggest trying to terminate it on your own - or you may get an EXPENSIVE lesson from a judge!

Not sure they can qualify easily again.

The leverage is a little lower and rates may change, but a DSCR is still possible provided you qualify.

If one is going to spend money on training learning how to present qualify and CLOSE is the skill agents need.

You can use that income to reduce your DTI and be able to qualify for a higher mortgage, if necessary.  

if you qualify, using the VA for a small multi opens up more opportunities as an asset vs investing in SFR.  

Down payment can be higher than primary, but the good thing is that you won't need that much income to qualify because lenders can you 75% of the market rents for the units of the property.
