You will ALWAYS find tenants willing to rent a new townhome in that area; however whether you want to rent to them OR the amount that you can get will vary. There is always a risk of a problem/deadbeat tenant.

You can’t rent anything new for anywhere near $1500 in that area,
There are always people who have no interest in buying (for various reasons) and will pay a top price to rent a nice place.

I don’t think it makes and sense to consider buying an $825K place that would only rent for $3000 mo.
How much is the HOA that you will pay ?
Don’t forget that your property taxes will be $800+ a month.
You will need cash out of pocket every month, in which case your tenant is not paying down your mortgage (you are)

If you’re open to the idea, look at other parts of the country where $800,000 will buy you an apartment building (10-20 units or more) that can gross $8,000 a month rent (or more)
…..After expenses and management fees you could have a nice return and greater depreciation than an OC townhome.
There are good property managers out there and you wont be involved in the repairs/maint other than making decisions.
