We have tenants looking to buy a house, and we were considering selling them our rental with a lower interest rate than current market rates.Does anyone have experience doing this? 

Is that expensive? 

Anything less I'd raise eyebrows.This is what you should do you when you get a sizable windfall $10MM++, if lower and looking for tax deductions get an STR underwritten as a LTR. 

The key here is that you do not have a primary housing expense.

I think the HOA fee will tank your profitability.Run the numbers and see what you could bring in minus your expenses to see.

I was looking for a market that had a lower barrier of entry and was investor-friendly. 

With lower LTV, rates can be near 6's and up to 8's with higher LTV.

Another one is "Sub-To"....but be careful of buying into these expensive "Sub-To" guru programs.

Most of them lie about what they've done, when they did it, and how they did it.The time-proven method of building wealth is very simple: earn, save, invest.There was a time when you could buy properties cheap, rent them for more than your expenses, and then rinse and repeat.

Expenses and taxes can be a confusing part of real estate.
