I have come across multiple properties - typically houses that require rehab - where the seller is not the owner of the property but what I believe to be a wholesaler or investor who has been assigned the rights of the property to sell to an end buyer (me) for a (substantial) fee.

Websites like Zillow, Realtor.com, and Redfin offer valuable insights into market trends, median prices, rent estimates, and historical price data.

I typically have enough time to do this myself but also value my free time with family.

Every time i put an offer on a house, i get told that the agent or the seller will not allow assignment, which kills the deal immediately.

@John Cava, feel free to contact me directly; I'll do my best to help and can offer a complimentary 15-minute consultation. 

(And offered to pay to fix it)What concerns me is she did not reach out to the person below or contact anyone .

I finally received a demand letter from a "nonprofit attorney" representing the tenant, claiming that the tenant was living in uninhabitable conditions—typical for a non-paying tenant, I guess—and now she wants to "renegotiate" the rent and keep living in the same space.She has been filing complaints with various government departments, but all the cases were minor and have been closed.

We have enough capital now to purchase a property and and we are blessed to have capital left over every month as well, which we typically invest in CDs.Here are our current options: 1-Buy a turnkey place that has nothing to do with mom for cash flow of $200-300/month plus potential appreciation, overall ROI of 15-20% 2- Ask mom if she would move closer to us in San Diego, buy a small place here, have zero cashflow but at least we have another property in a great appreciating market and are no longer spending the $800 on her rent3- Buy a place for her in Orlando, same scenario as above but obviously a lesser mortgage since its FL and not CAWe found a great turnkey company we liked so if we do option one I think we will use them, but it just feels like if we do that we will still be tossing away what we currently pay on her rent. 

@Bryan Sharples, You don't give us much to go on, in terms of what you have to offer. 

I'd recommend either going for a legal 3-4 flat or a 2-flat that is duplexed down or up.It's a good idea for your agent find out if any of the units are "non-conforming" or "illegal" before you take the time to show the property and make an offer.
