From my understanding, as long as you intend on doing a STR when you close, there are no rules against changing your strategy after closing, especially if you find that something else is more profitable.So in our case, the lender determined an STR would bring in ~$3500/month (with all of their conservative factors), but now that we operate it as a huge 3300 sqft Co-Living property, it actually brings in $7000/month.

I have only been doing this for 5 years but what I have learnt is that it takes money to make money.  

You could offer cash for keys to get her out-NEVER hand over any money until they are out and you have the keys and signed paperwork that they are out of the property. 

I will add that to your question of 10% or 20%, you need to ask yourself whether you need the cashflow or not. 10% down would leave some money with which to buy more properties.

You've earned $132,000 more by splitting your money and leveraging it.

The predicament we are in is the property is not in the condition to charge that much for rent and we would also leave a lot of money in the deal once we refinance if we cannot get in there to fix it up.

I fired them last year.I just opened my mail to find a notice from a COLLECTION AGENCY stating I owed them money.

We actually had 13 insurance claims from that one storm. 

Sometimes occupants still live there and eviction is not easy, and I have even heard a story once that the yakuza are involved in the construction and real estate business and exorted money from buyers through occupants in these properties. 

If there’s specific projects like electrical we get a project specific estimate after we put it under contract prior to the earnest money going hard.
