Will it immediately move to full transaction price, or does this jurisdiction use some sort of flat percentage increase.You should know how frequently the property will be reassessed thereafter.

on top of that there were at the time close to 40k vacant homes.. so all sorts of mortgage fraud..

I suspect anyone telling you that you need to tap into underground markets is trying to sell you a marketing scheme of some sort.

just don't do a lease. as others have mentioned, this forces the buyer of the property to take over the lease (if its even allowed/ they qualify) and it certainly does make the property a little tougher to sell. i'm also doing a house hack, and here in CA, its made a world of difference for me. the bulk of our energy usage is in the summer when we want to run the a/c. my bill stays a constant $228/mo (i pocketed the tax credit and simply financed the panels after that grace period). instead of getting an $800 bill in the summer months, we run the a/c at a constant temperature 24/7 on auto, stay comfortable, and i typically get a little bit coming back at the end of the year. don't expect to pocket this "little bit back" by being conservative with your useage, it sort of is a use-it-or-lose-it situation... i think i got $54 back this year.

So, because of this a lot of the "affordable" condos you will see in DFW have financial issues and you cannot get a mortgage loan on them, and have to pay cash. or, maybe get some sort of non conventional financing that is much more expensive requiring 25%+ down. 

Iwhen underwriting we also want to know the exit strategy of the borrower to make sure they are not limiting themselves to a single exit I honestly don't know how enforceable it is, but 24 hours to respond to any sort of communication is more than reasonable in my opinion.

I keep it updated with all sorts of local stuff.

Same guy handled a triplex rehab (the one with the theft), and that's where he took money that he simply pocketed or used in some sort of Ponzo scheme to pay off other debts (I have no way to know, but the money did not go to contractors or to continue work at the site).

Then there is a sort of echo chamber where social media spreads this idea to more and more people and somehow it becomes realistic. 

For data, I rely on PropStream and ListSource.To stay organized, I label and sort leads by status (hot, warm, or cold), set daily follow-up reminders, and always prioritize hot leads.
