Downside on FHA is the Self Sufficiency rule where all units, taken at 75% of gross rents must at least equal the total mortgage payment including property tax, home  insurance and FHA monthly mortgage insurance.

I have to figure out the cost/investment of building a home from scratch vs potential rental income, etc. 

I live in southern Ontario in Canada, and here if a tenant doesnt pay the water bill it goes onto the landlords taxes.

Probably a good thing for US tax payers since we are in a seller's market.

Then, move into Show Low STR for two years and Sell for up to $250,000 Tax-free.

Currently I am trying to get through the process with Flagstar but I am hitting a wall with my DTI and they are stating they are unable to use the income from Airbnbing as part of my income even though I report it.Any help is greatly appreciated!

You live in it for 2 out of 5 years and Sell for up to $250,000 Tax-free.

My property taxes are high - around 9k a year.I’ve been out of touch with the market this year dealing with an illness and I’m trying to make the best decision cause this is my lifetime investment and extra income.

Right now as a renter you're paying 100% interest and personal rent isn't tax deductible. 

Will title insurance still cover any leans/unpaid taxes if any?
