As Wix is an annual subscription about to renew, I decided to take this as an opportunity and make some improvements. 

So since it was less than 50% of our total joint assets it was an easy choice for me to just keep that as 'part of my half'.One interesting side note; do your own homework in ADDITION to seeking professional help.

My client and the seller set up a joint venture, they both co-sign on a loan, I'll lend the $50k in rehab (I'll do 100% because the seller is pledging the house as collateral), then when it sells, the loan gets paid off, the seller gets his $150k for the house, and then they split the profits equally.

What to do daily to improve from yesterday.  

The Tenant/Buyer shall have the right to make such repairs, maintenance, and improvements as Tenant/Buyer shall deem necessary proper or desirable.

Did you budget for the tenant improvements and leasing commissions that comes with signing office leases? 

We are talking the mortar joint of one brick....  

The costs of such maintenance and repairs shall be allocated as follows: *The cost of repairs, maintenance and improvements, which are less than or equal to Five Hundred and no/100 Dollars ($500.00) per repair shall be paid by Tenant.

I am interested in ideas for improving the curb appeal of this property.

There are lots of Joint Venture programs out there; Dani Beit with Simply do it and John Majalca with www.texascashflow.com; just do your homework in getting investor references (not the people who work for them like lenders or title companies), check them out if they say they are realtors (check license), google their name, phone and emails (make sure they are not scam reports about them.
