For the District of Columbia, is there a template or any advice on what works to challenge property tax assessment increases?

Network with other professionals for insights and potential deals.

Doing a refi now would move me from a 4.5% interest rate to somewhere in the high 7% to 8% range, so I am thinking of potentially selling.

Requiring an application before showing the property may deter potential tenants, particularly given the prevalence of scams in today's rental market.

Work on your numbers - be sure to calculate potential cash flow and ROI.

@Joe Mills If you're just looking at the mobile homes individually (as personal property not attached to land), a good place to start is the tax assessment for the homes. 

While it is expensive, it more than makes up for the headache and potential mistakes that one would make from doing it on their own.

Title insurance insures against many issues that could come up later, but they will only issue this insurance after a title search that shows there are no known title issues or if there are issues you could potentially get insurance that excludes those issues and assume that risk yourself. 

Hey @Jeramey Rogers, what does the special assessment cover?

I wish I had an easy way to validate the Probate data since they seems to potentially save the most time for those leads.
