We are looking to do more in the future with them as I am very bullish on multi-family investments. 

Two groups that I will consider investing with again are Colony Hills Capital for multi family and FNRP, which specializes in grocery and big box store anchored retail spaces.  

DSCR or Fannie/Freddie loans can go up to 75% on single family homes, multi family homes (2-4 unit) max at 70% if you stick with Fannie/Freddie.Other things to consider would be:Paying points for a lower rate vs higher rate with no pointsIf going DSCR - Prepayment penalty term (0-5 years)The lower the loan size ($200-250k and lower), you should consider paying up to 2 points and doing a 5 year prepayment penalty if going DSCR.

Selling before death would be a costly mistake   - you did not explicitly state this was not a multi family but it seems likely from your description.  

Also, you don’t need a business license just to look at properties, but if you buy a bigger property, like a multi-family unit, you might need a certificate of occupancy, depending on the local rules.For business trips, most expenses can be deductible, but if it’s part personal and part business, you can only deduct the business portion.

Truthfully it is really pretty easy if you put the right systems in place.

While they cannot be considered rooms, they will bring in an additional $$ each and every month.If you have a mixed-use or multi-family, consider adding a laundry room, vending, etc.  

I'm researching/looking into Freddie/Fannie financing for large multi-family now.

I'm building my systems.

Small multi-family property is where I would start.
