They may also challenge the sale (maybe they weren't properly notified.)I suggest you read the tax sale laws in your state. 

I worked with two amazing Brokers (Travis and Patrick from Savvy Ent.) and an outstanding loan officer (Isaiah from Cornerstone Mortgage) who really helped pave the way.

Check out @Paul Moore (Looks like that didn't link properly).

I’m a mortgage broker and investor about 45 mins south of Cleveland, happy to connect!  

Make sure all your interactions with her on via email or text - to protect yourself.As @Greg M. mentioned, going to guess YOU are not giving her proper notice as legally required to enter.

So the loan officer has no idea what they are doing likely because they have never written a mortgage on a condo. 

With a locked-in low mortgage rate of 3.2%, and about $100k in equity after expenses, I'm contemplating my next move.

In DC proper, probably 90% of flips are bought right off the MLS.

They owe about $150k on the property and pay about $1500 for the mortgage.  

If I didn't find a fund I liked I would look to build a team of professionals that were intimately familiar with how opportunity funds work.In a nutshell, you can pay zero Capital gains taxes if you invest the funds properly.
