I have 880 credit score, decent savings, and no other debt except for 300K mortgage on my primary residence (worth $1.5 million).

Repairs made while the property is your primary residence are not deductible, but improvements can increase your cost basis, reducing future capital gains tax when you sell.

It's a quirk that very few areas of the country have.Both the city and county have their own areas that have Section 8 residents, but the Housing Authorities that handle the programs are different. 

The parent must file a gift tax return annually, and any remaining balance is included in the estate.If the home was your primary residence for at least 2 of the last 5 years, you may exclude up to $250,000 ($500,000 if married filing jointly) of capital gains from taxes.

I have a HELOC on my Texas primary residence and am considering a house hack for my next purchase.

Investment Info:Single-family residence buy & hold investment.

Been a lifelong resident and investor here since 2009 Ill send you a message 

Would the buyers/borrowers be purchasing with the intent of putting a mobile home on the property and making it their primary residence?

I am a long time Little Rock investor and resident.

@Kris TohovitisI wouldn't recommend using your cash to pay off the mortgage on your primary residence since you can likely get a better return on that money by investing it.What's your buying criteria for the multi-family property?
