Price of building a 4-plex vs 4 log cabins

[Pedro Rodrigues]

Hi everyone this is my first time posting. I'm as new as can be to investing in real estate. I own a duplex in the upstate NY area and I have been pleasently surprised at the cashflow this first year- about $14000 after expenses (short term Airbnb rentals for now). I'm primarily aiming at cashflow at this stage. I'm considering building more units on the land and, quite frankly, am a little disappointed by the construction prices. I've read online that multi family units are cheaper to build but I cannot find a builder that would put the 4-plex here for less than 180k a unit. So I have two questions for you:

1- Am I just hitting the wrong companies and the estimates I'm getting are inflated?

2- What do you think of, instead of a 4-plex, building 3-4 log cabins (2br/1ba) that I could lease 2 and Airbnb the other 2? I can build these for about 100k each.

Any help with these questions or any other advice on how to expand from here would be greatly appreciated.

best regards,

Pedro
