Always looking to partner up but you have to be able to get into the water with me.

Having trouble analyzing this deal as there are so many variables and I do not have the experiencing analyzing deals to make me feel comfortable taking the risk.Purchase price of the land would be $250,000 not including closing cost or fees, and construction for a new 3/2 home with an attached 1/1 ADU is estimated to cost around $300,000 - $400,000 finished.

Driving for dollars can be an effective strategy the costs (gas, time, energy, materials) have to be added to the deal analysis. 

In that sense STR investors can make markets more efficient by picking up housing units that most typical buyers look over. 

The original cost basis was $645,000.

Costs have gone up a lot and with the higher interest rates, deals don't pencil unless you have higher down payment amounts. 

Both occupied units signed MTM agreements per my request.

How much does it cost? 

Already saving up for a 3rd house.  

My 401k is set up with uDirectIRA.
