Though my real estate business focuses on multifamily housing, this topic resonates deeply with me.I remember talking to my father about why he lived at home after graduating from college in the 1950s.

Although I don't think you could do that and charge monthly electric costs too.

This is where your costs will come into play.  

I have noticed an interesting trend that's been more and more common since about 2018. Buildings selling for example $300,000 which need $150,000 of work but the ARV is only $420,000. Maybe people buying and not fixin...

Unless your mechanically handy your maintenance costs will eat you up.  

Once everything is set up, you'd do everything for your business through your LLC, including paying bills and taking payments.  

With the current market, I will not be able to make my required cash flow after paying all operating cost including mortgage, vacancy, property tax, insurances, maintenance cost, no need for a property manager because I can manage it.

I later heard but never exactly why, that the place was an absolute money pit and the buyer, who was very experienced, regretted buying it big time.It is interesting, but I ALWAYS do at least a bit of research on the prior owners and have found few "hard luck" stories, at least as far as either higher or high priced single fams go, they're by far the same story where the owner makes the financial decision to walk away, mainly due to the insane HELOC's etc they were giving out, like 125% of home's current value back in like 2006, so now they'll owe literally like $750k on a home that IF in great shape would at best fetch $500k, PLUS they trashed or semi-trashed the place, so they'd be really lucky to get $400k as is and often they may be business owners or whatever and have a relationship with a local bank who will then know "the whole story" behind the big hit they take to their credit score and not treat it nearly as harshly as the average Joe, who's practically banned from even entering the bank for years!

I am putting 20 % down ( 90K) but I see there is about 27K in fees and closing cost.

I am willing to share everything I know for the cost of lunch somewhere in West Hartford.
