You will need to know the current rents, when the last rent increases were, if there is rent control in your state, and know what the monthly expenses are on the building (typically they include water/sewer, garbage, insurance). 

The issue with calculators is "Garbage in = garbage out", you can have unlimited calculators but the inputs (costs, ARV etc) on preforeclosures is typically unknown on what it costs to renovate, so without that information no calculator will be helpful.At the end of the day, do not need fancy calculators to tell you income - expenses = earnings. 

There are a fair number of outfits in Detroit that will do garbage renovations and slap high voucher S8 tenants into the properties and market them with high ROI to out-of-state investors.These are easy for locals or experienced investors to spot but a lot of people get sucked into them.

Lots of garbage. 

When I heard that, I spoke to his tenant next door to me, and for the use of my driveway, swept the hallway, stairs and sidewalk, take the garbage cans out for sanitation pickup and retrieval.

So also the question for us of "how much is it worth to not have bad neighbors".Full background >>The tenant left a few weeks ago, leaving behind every bedroom full of garbage (to the ceiling), smoke smell in the house, broken toilet, ceiling was never fixed from water damage a few years ago, floors have dried cat vomit and rotting garbage stains, couple broken windows, federal pacific panel (fire hazard), they dont know if the heat works, the list goes on...The seller overpaid for it in 2022 as part of 3 pack of rather delipated properties in town.

There are lots of people that have all this garbage blow up in their face, get in trouble, end up in court with the other party, etc.

And how was this Freedom company so capable of making the investment property look so nice when they wanted to sell it to me but when it came time to re-rent it, they presented it like a piece of trashed garbage with regards to the flooring which looked so incredibly awful?

We also write in a "you break it, you replace it" clause into the lease about the garbage disposal as well.

Jerry Norton is a predator scam artist every body dont buy his garbage.
