@Jordyn OhsThis is a loaded question as it really depends.

I’m going to disagree with @Chris Seveney and say whether an assignee could force a sale directly would be a state law issue and heavily dependent upon the contract terms. 

It seems simple, but it's not a DIY thing because of technical rules that are different depending on circumstances.Or, you can pay a lawyer to file an ejectment lawsuit, the developer can pay a lawyer to defend the lawsuit and redeem, and the developer will also be responsible for reimbursing your legal fees, plus interest. 

Depending on how much money you're willing to pay, it might make more financial sense to use another platform.

Property Transfer TaxOne of the key costs associated with purchasing property in Germany is the property transfer tax, which ranges from 3.5% to 6.5% depending on the region.

@Edgar Duarte Depends on if you prefer owning real estate or want to be invested in the stock market.

Depending on the market you invest in, you may have enough to go all cash on the first deal and refinance to put money in the second deal. 

You'll create cash flow every month and then at the end you'll get another bump of $40,000 or more depending on your loan amortization schedule.With the 70k down payment buy a house from wholesaler with a hard money loan that is well below market value.

Is your income considered variable in nature depending on job sites and that you do not work a set amount of hours per week?
