My wife and I used to do flips in this area, and I have a couple listings along with long term rentals I manage in the area..For the co-host, they typically do not handle permitting and other items like that (this can be agreed upon between you and the co-host.

You're also going to need survey and engineering work to get the permits done for putting in the utilities to the buildings, flatwork and other improvement requirements around the buildings.

I dont like the ideal of prospecting 5 days a week and im a single dad so the weekends are a no-go. 4 days for calling 3 days for follow up and appointments. 

Duplex have different zoning that may permit additional units.

Microsoft Excel, and most budget or free online bookkeeping isn't going to cut it in this situation.For the rental properties you own directly, I often tell clients and prospects that a P&L in Microsoft Excel is just fine and a balance sheet is not necessary for tax purposes. 

Quote from @James Kiny: We are a welcoming group of investors -seasoned and prospective - looking to share ideas, talk over problems and celebrate successes of our group members.

Be careful when someone gives you prospective figures to understand what the data represents.3. 

Most of the prospects offering this to us, disappear when we tell them they still have to go through our full application & screening process. - We almost feel sorry for the foolish/naive DIY landlord that inevitably falls for their sob story and accepts them.We have had 2-3 that have gone through our process and so we accepted their multi-month payment.

Instead of depending on buyer agents to drive prospects from house to house, prospects would tour houses themselves, and unlicensed “door-openers” would admit them.

For vacant units, consider virtual staging through VirtualStaging.ai or something like that to help prospective tenants visualize the space.Hope this helps expand your marketing toolkit.
