If both your names on the deed and you file a joint tax return the the two of you (or more accurately your joint tax return) are really seen as the taxpayer for that property because it is reported on your joint tax return. 

It is forgiving because it is easily patched up with joint compound and sanding.

Like a Joint Venture in an LLC .

If you live in the home for 24 months out of the past 5 years, you can exclude up to 250k of capital gains from your income, or 500k if married filing jointly.

As others have pointed out,You can only take the section 121 exclusion for the unit that you live in - If the 'allocated gain' to your unit is less than $250,000 / $500,000(married filing joint), you don't pay capital gains tax on the unit you lived in.However, the unit that you did not live in is not eligible for section 121 exclusion.

Draw a flathead screwdriver around the perimeter of a ceiling and in the joint between trim and wall before painting to get a good, thick indentation in plaster ane drywall to help you cut in.

not really after taxes and realtor fees.I think we are talking about the same deadline: If you did not live there for 2 years of the previous 5 years, you cannot take that 500K subtraction from your capital gain, assuming you file jointly.

(and yes, DSCR are personally guaranteed) The number of financed properties calculation includes:the number of one- to four-unit residential properties where the borrower is personally obligated on the mortgage(s), even if the monthly housing expense is excluded from the borrower’s DTI in accordance with B3-6-05, Monthly Debt Obligationsthe total number of properties financed (not the number of mortgages on the property nor the number of mortgages sold to Fannie Mae), with multiple unit properties (such as a two-unit) counting as one property;the borrower’s principal residence if it is financed; andthe cumulative total for all borrowers (though jointly financed properties are only counted once).

Combine this househacking with joint venturing on some commercial property around the same market (5-20 units) with a few other investors that compliment your skillset and viola, you will obtain 30-50 units in 3-5 years.
