And the plan has to have numbers that workI'm assuming that you plan to purchase and convert these commercial spaces into residential.

You still need to drive traffic to that site and convert some number of that traffic into leads.

Also, all tenants have been there for awhile, you'll have to add some money for light rehab for three of the units: paint, floors, maybe some appliances, and to remodel and convert the 4th unit to a 2bed/1bath unit. 

We are also interested in multifamily homes that can be converted to professional office space (e.g.

Roof, all plumbing, all electric, all HVAC, all gas lines, adding bathroom, moving walls, all windows, huge deck addition, drywall every square inch.

I was woundering what could those be converted to?

I've been using Utilitech Pro fixtures in 3500K.I use the 12.6 inch ones in hallways and closets.

If you give a few inches soon they take a mile. 

Other downsides, heater is oil heat, and no central AC (just small window unit), large yard is very overgrown with Himalayan blackberry bushes, and no garage (converted garage to living room space).Upsides: decent condition wood flooring in bedrooms and about half of the living space area, newer vinyl windows in most of the house, outside siding in great shape, roof looks to be in good shape, and the most important upside is the neighborhood, excellent area.FinancialsThere are already multiple offers on the property and they are accepting offers until Monday morning.  

For my mobile devices, I use many applications such as the ones listed above, plus the following: Docusign - used for paperless document/contract/tenant form signings.Apps such as PDF Expert(pdf doc modifier) , PDF Office(pdf doc creator) , PDF Converter, Spark Email, Documents(cloud doc integrator), Calendar 5, Scanner Pro, Printer Pro all created by a company by the name of Readdle.
