DSCR loans are a great option for anyone that doesn't fit the conventional "box" - DTI isn't a factor, no employment info needed, no W2s, paystubs, tax returns, 1099s, etc. needed, you can close in an LLC if you want to and many lenders don't report to personal credit, so those loans won't affect your credit score/DTI for any conventional financing you might pursue in the future.

You'll pay a little more up front, and avoid headaches down the line. 

Calculator should provide amount of conversion  tax payments needed, one or multiple conversion options,  Medicare IRMAA impacts, various investment percentages of Roth growth vs IRA growth, and RMD amounts with associated tax bill.I’ve seen numerous CFPs hawk their services for $5,000 or more.  

Unit A is about 100 years old and Unit B is almost completely new.Pros:-The duplex is in a very desirable neighborhood with home value appreciation year over year at about 50+%-Rent is also in high demand within this area-Cash flows well even with high interest rates and increasing property taxes-Home is price below average cost per sq ft-The house has been renovated and some parts of it has been remodeledCons:-All issues are with Unit A, the 100 year old unit.

There are a few different options/ methods (avoid the dry well in this case).

How will taxes work for each of us since we are in different states?

@Chris Seveney the Detroit Land Bank sells tax foreclosed properties that Wayne County sells to the City of Detroit (more or less).These are NOT lender foreclosed properties.

But, if you are younger than 59 1/2, you could get whacked with $50k in tax penalties alone. 

The difference between a $1000 exchange and a $1500 exchange is insignificant when compared to the tax hit if your exchange is done improperly. 

You certainly can 1031 exchange from CA to Hawaii, although the California Franchise Tax Board will make it a little more annoying by forcing you file a new form (Form 3840) each year after you sell...failure to file the form will result in taxes owed.
