Posting this duplex that I found here in the heart of Eastern Michigan, I've been frequently trying to run numbers on duplexes and investment property listings as an up and coming agent and investor to try and gain whether a deal is good or bad.

I have several contacts in new home construction, architecture, land developers and community organizers who help me locate buyers and sellers.

Can you then decide to list and sell the house two months later...yes.

I call it that because most commonly the listing agents call me and says "you mother f...." to me in response, lol. 

So, when we call the landlord the tenant has listed on their application, we can ask questions to uncover fake landlords.

Quote from @Rick Im: I recently submitted an offer on a house listed as having 5 bedrooms and 3 bathrooms.

What worked for me was listing on multiple platforms - Facebook Marketplace, Craigslist, and even local community bulletin boards.

We do have a realtor and lender but what are other ways or other people that can help us find good deals say before it’s listed? 

And for furniture included, did you just list all the furnishings you provided?  

Look at commercial and industrial listings with realtors.
