I'm pretty sure that if you ask OpenDoor, they'll have some spokesperson say that all is fine but then again, they really can't come out and say that they are bleeding red (they have to say that they are ok) or else this will cause panic amongst their investors which will lead to a drain on their funds. 

(This home has only been owned by 1 person.)Since there is possibility that I may refinance this home after purchase and also may end up selling it at another, I'm concerned this will come back to cause me issues later on.My concerns are 2 fold. 1.

If you borrow against a HELOC to purchase an investment, that borrowed money will count against your debt and could cause you to be over-leveraged.

I'm a bit concerned about the unit not being able to rent for the  same amount as before, did something happen in the market to cause this? 

Regarding attempting to cancel the redemption, I strongly suggest you let the SDAT process run its course or you'll cause issues regarding the insured deed of trust and thus the refinance itself.

You just had some bad guests to flush stuff down the toilet that caused your repair bill. 

This alone may cause them to move on to the next property. 

But part of the renovation process is eliminating those headaches from the house itself now, so they don't cause problems later.

It's helpful but also can cause you to go down rabbit holes with research and so on.So, to answer your original question, I am on a similar path to saving money for a down payment and to have some cash reserves and I am using Betterment.

Inflation isn't necessarily caused by new purchases, a large component of it is a psychological expectation of higher prices.As far as new purchases leading to higher inflation, I barely even saw a slowdown in my market (North Dallas) and very few price cuts.
