I served a notice of non-renewal to my tenant with the lease ending in June.

I agree with you.Some wholesalers will have people come to them stating what they are looking for therefore eliminating the need to advertise.I have already noticed changes in the local wholesalers in my area.

Actually start in the deep end and begin working on the projects (flips, brokering, wholesales, etc.) that you're wanting to do and you'll notice that you'll find your team along the way.

Even though i am 26, employed, have savings, and a stable job - too much protection is never a bad thing.However, i find it very sketchy and somewhat car salesman-like that all these companies keep spamming me with mail and warning me of "last notice or else i will never be able to protect my mortgage ever again."

The people I've known who have been successful in this business- successfully in their own terms of it, meaning owning a rental or two up to unbelievable wealth in real estate, all, all, all had a tight REIGN On their business (Notice I said business, and not investment- because to buy this business costs money, the money is invested in that you might be able to get that money back unless you lose the business to the bank or it is destroyed by your customers).

Well, if she won't leave voluntarily, then you'll need to post a pay or quit notice on the door or hand it to her.

I noticed there was a minimum of $250/month and was willing to pay the minimum.

But it also went on to say with a property lawyer the person who placed the restriction or the heirs may be able to “foreclose” on the property and reposes it after sending a notice to cure that is ignored. 

Notice there has been NO correction or clarification by Biden administration has there?
