I am considering working with a property developer in NJ to buy land, build a duplex/triplex and sell it (6-9 month time horizon).  

I am only an aspiring investor, but I am a local resident of Niagara Falls, NY and I am hoping I can shed some light on your question about the winters:) I have worked in the tourism industry in the past, my husband still works in tourism.

Rentals also build equity through tenant payments and appreciation, with profits taxed at lower long-term capital gains rates when sold.

The rent goes back into my ROTH account, builds up and then I buy another property when I can.

Wish they would build houses with this style of architecture still.

@Kyle Cross you claim to know a lot about the industry, but your questions are vague and so is the info you've provided.Not sure how managing 8 units doesn't, "require much management"?

Bringing the seller in on the deal not only gives them an opportunity to benefit from the upside of the flip but also positions you as a problem-solver, which can build trust and goodwill.

Typical equity build up time is 5 years, depending on your market.But can you purchase another rental using your own capital?

Coghill they are trying to take care of several things:1) Approval to access credit reportsA video tour of my home office (required by the credit repository to show security, so access to office & computers is limited to avoid data theft)Credit checks on me and my partner (required by the credit repository to make sure you are not criminals looking to steal others' data)Copies of the deeds for every property we own (required by the credit repository to confirm you aren't just self-serving)A copy of my partner’s home lease and utility bills (required by the credit repository to prove his legal address, so they can pursue him criminally if he steals data)Business phone bills (required by the credit repository to prove an actual business)2) Approval to use banking ACH system to accept tenant payments and pay ownersBusiness phone bills (required by banking industry to prove business legitimacy)A signed letter from the bank verifying our accounts (to prove legitimate business banking accounts.

Start running numbers on potential deals to get more comfortable, and build out your team—like a CPA, property manager, and lenders.
