I'm trying to look for a course on how to better understand valuations and also tax liens in different states, so as to form better & tax efficient structures under which to invest in different states. 

Partner Driven’s efficient project management ensured on-time, cost-effective improvements.

Totally not efficient, but its something we may have to do.

Speed and cost/tax-efficiency are usually mutually exclusive.  

I tell every Chicago investor who calls me about Milwaukee to stay in Chicago - the economic delta is just not big enough to take on the remote cost and efficiency burden.

Rex (Real Estate agents and sellers to optimize listings, attract buyers and close deals efficiently) 5.

We've found it has superior reporting features, integration features, and is overall more efficient to work within than other REI-specific software.The downside is QBO is not set up for REI so you'll need to do that or work with an expert to ensure it is set up for your business appropriately.Something else to keep in mind is your entity structure and how your entities file tax returns.

Any recs for something that efficient and clear? 

Real estate is a pretty efficient asset class.

Not all lots are cost efficient to build on.
