Typically seasoning means that the funds have been in a bank account for a set amount of time (usually 60 days), so ANY lender should love that....I thought maybe you meant un-seasoned funds?

I checked the property but couldn’t detect anything unusual.

They expect you to live in one unit, BUT I have never heard of anyone from the lender go and  check in on you to see if you are actually living there. 

Another way to look at this is......1) figure out what you want to make as a net profit, 2) Do a quick check to see if this is within local averages, 3) Set your pricing at that higher rate, but keep your occupancy lower.You make the same money with less effort or risk...This might not work everywhere, but it's certainly worth a try.

Check with the county about permits and what is allowed.

One of the best places to see what's out there in your area is to check Airbnb AND Pricelabs. 

I'd check local STR FB groups and see if you have a local Real Estate Club.You can offer your services there, maybe for free in exchange for the experience.

You can also check their reviews online at Google, Facebook, or Yelp.

Once you hit a certain number of loans (check with your state dept of banking and finance or dept of business regulation), they might require you to have a license.
