I would then work to renovate the bad unit as quickly as possible.  

Real estate investing can absolutely be a game-changer when it comes to freeing up your time and helping shape the community you care about—especially in our beautiful region.You’re on the right track by diving into BiggerPockets.

My other concern is that home prices on Long Island appreciate quickly.

A prudent investor doesn't seek quick riches through shortcuts.

You need a repair partner who can get out immediately and has quick access to replacement parts (if not already in stock). 

@Keetaek Hong I have a lot of clients who are facing the same challenges but they understand the long game and that it's imperative to build a portfolio, With that lowered interest rate I mentioned you are looking at 30% down and including PM fees will typically have you around break even or barely positively cash flowing.

My biggest advice for people would be as follows.Know why your in the real estate game, and why a specific niche.

There are people who have an entire business helping you set up and design a STR relatively quickly (3-7 days) depending on size of home and complexity but you are going to be paying a bit of a premium but you do save on the headache.

There's lots of opportunities in developing neighborhoods, but also seems a bit saturated at the moment.Also, definitely budget security (remote control cameras, alarm system, etc.) for your properties, as there are a lot of people who occupy themselves by breaking into houses and stealing anything they can sell.Lastly, there are a ton of contractors looking for a quick buck.

The ones that really interest me I will respond to and of course those who donated to my charity :)  and or send me gifts :)  But those who just think a quick sentence and we owe them  Nope just say thank you but I no longer do that.
