There’s usually not more than one investor with interest in any parcel so there’s is absolutely no incentive for the investor to pay a “wholesaler’s fee” in this scenario.In the scenario where the land is ready for development, and the economic conditions make development a profitable activity, the land owner has already been approached by the developer or multiple parties with offers to purchase.

Larger owners tend to analyze market rents monthly or even weekly and manage rents (or incentives) the best way they can.As long as the owner is engaged, the chance of adjusting rents is higher.

This will be my first home purchase, and I am aiming to invest in multi-family properties.What should I be aware of when purchasing a multi-family property?

Seasoning for ownership typically starts on the purchase date.

The deal was successful and later on we sold the property at a significant profit and 1031 to something larger.
