@Richard Benjamin Wilhite, @Bill B.makes some good points about loan terms and the strict identification rules for a 1031 exchange.I would add from a tax mitigation perspective that buying the largest property possible will give you the greatest amount of cost segregation possibility and at the lowest cost since it would be one study rather than several. 

Once the cost segregation study is complete, will I be able to take a full year of depreciation or only a prorated 4 months? 

You could sell the property at the beginning of the year and buy a property/place that property in service (and do a cost segregation study in the same year). 

Study the market.

Looking for a real estate Cost Segregation Study specialist for my house in Virginia.

We have been studying Buffalo's market and it looks really promising. 

Note it often is not a result of significant NOI change (excluding some markets where a lot of new units have been added). 3 recent studies show it is cheaper to rent than own in virtually all of the largest US markets.  

3 recent national studies show that the rent to value ratio is at an all time worse (what they really studied was cheaper to rent than buy, but there is strong correlation).  

They have paused for 100 days until they reconvene to re assess and study more the impact.

I'm new here and I have spent a couple of years studying real estate investing strategies.
