I knew nothing about real estate or investing except that I should buy property and hold onto it.

Would I buy another one if I could in this very same area, I ABSOLUTELY would if it cash-flowed like my existing property. 

I am about to buy my first rental in Baltimore metro area.

If the property has STR history and this is your first time buying an investment property you may also push for an exception with a higher downpayment 25-30% along with other compensating factors. 

If the LLC signed the contract, and you buy the LLC to not have to record the real estate value, you are also taking on the liabilities of that LLC.  

For example Hover allows you to buy a domain for around $15 a year and a small mailbox for $20 a year.

There are pros and cons of MF and there are many successful investors that buy only single family or STRs. 

I buy in Dayton so I was curious and looked at their website.

Let's say the tenant has a horse and someone stops by the property to buy an item they saw on Craigslist.

In other words, if you buy a property thru one of these companies and later go to sell it after you fixed it .... many other local title companies won't be able to insure it for you.
