They claim to have owned four rental properties and a large house which they sold before coming here.

To give you some perspective on what those tax increases can look like here are some examples of the changes based on some of my properties that I own in the city:$4096 -> $5522 (+1426)$3850 -> $5516 (+1666)$3835 -> $6283 (+2448)These are only some examples, but all of the properties that I own have increased in its tax assessed value, therefore drastically increasing the taxes per year and decreasing annual cash flow.While tax assessments are normal it seems that this is a very drastic effort to recuperate losses.

They will usually never own up to these facts - instead they will use the cover of "our corporate clients", etc - it's a big tell!  

Was it your personal account or a business account? 

I would suggest watching some youtube videos, come up with your own variation of someone elses script and practice it until it sounds natural.

If, however, that means you own more real estate in locations that you like, you get the magic of leverage + appreciation that results in a better long term return. 

Unless you own a couple of residential investment rentals already for 12+ months.

This means we need to buy under an LLC and not our personal. 

A little background, I own about 9.4 acres in Hermitage, PA where I house hacked the property.

@Calvin Pringles This is your own thoughts and opinions, every investor have their own investment buying criteria.While Accessory Dwelling Uni (ADU) is a simple easy solution to competing for a small multifamily, they do have their own drawback as well.Goodluck to everyone trying their best to make a deal happen.
