If I purchase a building with rent-stabilized tenants, are there any legal ways to de-stabilize the units, especially after doing significant renovations or rehabbing the property?

Congratulations on your first investment purchase! 

So I am looking to see if anyone has ideas about what options I should consider to gain more experience in real estate investing as I get my finances up to make my first purchase.  

Secondarily, if I had a buyer for the land before I close, could I structure the purchase to include them without doing a wholesale deal?

I would recommend that regardless of market you decide to invest in that you find a fellow investor/realtor that can help you purchase in the neighborhoods that make for ideal long term rentals.

Purchase price: $550,000 Cash invested: $145,000 Sale price: $915,000 This was a home run for a long term (5 years) buy & hold investment property (I specialize in this area). - Initial investment of $145K (DP+closing)- It had one tenant for 5 years and 3 months (no turnover), and the tenant paid off the mortgage and expenses in those 5 years.- I spent around $30K to do upgrades before selling.- Sold it for $915K after 5.5 years (received $442K at the closing)- Did 1031 exchange and bought 8 SFH in NE & AL worth of 1.6M (brings $4k/months income now) What made you interested in investing in this type of deal?

I a analyzing a cash deal for $420 that I will leverage after purchase leaving me with approximately $200k in cash plus the $100k in equity.
