Hi Kin,Three quick questions come to mind that would impact your situation.

Some folks have already given good advice, and I want to add a quick tip for how to get data on potential STR properties.

Real estate is one of the best mind-sharpening exercises in the investment world simply because getting it wrong there is no stock liquidation or quick way out.

His brother (the squatter) wasn’t going to leave the property without a fight.I showed up to the house with my acquisition guy, and things quickly got hostile.

I would try to portion that off as a separate loan that can be paid back quickly - you'd need to discuss your plan with the PML.

It is invaluable to quickly calculate a mortgage payment.3.

We have zip codes that have lower and and higher end areas within the same zip so not a good marker to use.Going along with that a lot of the neighborhoods are very street by street or change pretty quickly by block, so you have to be aware of that.

You can find the most recent sales price for the property on the local tax records website or by doing a quick search on Zillow.

I think that the attempt to scale super quickly is more dangerous than whatever the first raise is. 

Some get better, some worse.The answer isn't a quick "go here" an invest.
