It sounds like you are buying a boarding house (which is VERY management intensive, we don't manage them). 

The turn around would be intense, but on paper it's doable.  

I guess it can happen but as real estate goes I think this is by far the hardest thing to put together sustain and be profitable at.. other than a side hustle make some money occasionally if you darn lucky type thing.. folks I know that do this successfully spend probably 100 to 200k Minimum a year in mailers ALONE  and they have teams that door knock that get paid and Very robust back end systems.. etc etc.. this is a capital intensive business to do right.. 

That will be really tough.Part-time agent as an investor equals high liability for a broker and intensive time training them in most cases.I get many calls from agents wanting to park their license with me or they do just a few to no deals a year yet the real estate commission requires me to keep a ton of paperwork on them.At the highest I had about 50 agents but have pared that down considerably to work on my own deals.I still have some experienced agents that I don't have to spend too much time on.So do you want to be an agent or just an investor??

on the plots.Lots are always behind another property with existing road access.Lots are on a (steep) slopeI understand that constructions on steep slopes are probably very cost-intensive, which is probably the reason why these lots are relatively cheap.

I've been to countless workshops, bootcamps, and 3-day intensives.

Been to several meetings and signed up for their 3-day intensive coming up in September.

Jessica G.RE is an extremely intense subject to study.

So ultimately, wholesaling property in NYC is not impossible to do, however it is extrememly challenging and can take very long to find opportunities.Since I have no mentor in an area where competition is intense, I feel that starting out in NYC may not be a good idea.Nevertheless, I am still very driven to continue searching for opportunity and growth.

Short term rentals are very management intensive.
