Or is it calculated daily and the base rent increases after 10 days when the late fee hits the account?

Can not go wrong with a rental in Ashburn since the rents have increased so much. 

Putting that amount into it will only increase the loss.

That sounds like massive renos (ie new floors, painting...).Yes as you acquire more properties, the chances of having multiple vacancies (no matter how leases are staggered) increases.

Rehab costs, taxes, and interest during this phase increase the depreciable basis, providing long-term tax benefits.

How about the increased home insurance cost for a landlord policy?

While I’m open to both turn-key and fixer-upper properties, my preference leans slightly toward value-add opportunities where I can improve the property and increase equity or cash flow.That said, I’m also happy to consider turn-key options that provide immediate cash flow if they fit within my investment strategy.

The goal here would be to increase rental income.

This would greatly increase the size of your next downpayment.

We had nine months straight of increasing inventory.
