2.What are the best and most cost-effective solutions for managing this potential long-term issue?

Having watched many prior co-workers get paid, cash their check at the casino, and promptly deposit it all into a slot machine I can tell you with pretty good certainty that casinos don't have a positive effect on disposable income and good use of the existing income in the area surrounding :)Are there solid local employers OTHER than the casino in a 15-minute drive? 

This provides you with a safety net for any unexpected expenses during the rehab process while also potentially allowing you to secure higher leverage on the purchase price.

In effect, earnest money is just paying more of the down payment and closing costs upfront.”Keep in mind, this isn’t required, and it doesn’t guarantee your offer will be accepted.

Plus, having a fully paid-off property could be a nice safety net if the STR market takes a hit or occupancy slows down.On the flip side, if you’re eager to grow, saving for another property could be the better play.

I have a calculator (semi-ugly but effective excel sheet) I use to look at the numbers on all 1031 exchanges I’m considering.Let me know if you want help with the calculations

But, for instance, I sent them a notice of rent increase effective February 1 and needed them to confirm that they have accepted the new payment terms through our electronic payment system, and even after repeated notices, they are not responding.

I'm not saying the list is ridiculous,  because all safety concerns should be addressed.

.- there are ways to never pay tax on gains (1031, owe until death, etc)- cost segregation can in effect have RE acquired at no cost- sweat equity can produce additional return.  

Does anyone have any advice on effectively setting up temporary battery-operated cameras on a long-term rental property to deter break-ins and squatters while rent-ready repairs are being made before a tenant moves in?
