Am I allowed to ask for proof that the tenants are paying properly and on time? 

I think Worcester and Lowell is a very strong market as a second alternative to the Boston proper area.Alternatively, NH/RI properties have some of the same cap rates as long distance states but you can manage them. 

I focus outside of these loops unless it's an opportunity zone (many around southern dallas proper) and has at least 1.5% rent/price ratio.

Be carefull  adding central air to a duct system that was designed for heat only , it may not cool properly .

However, there's nothing to stop you from requesting an Addendum to include a course of correction if they are in breach of contract, with a term for establishing the landlord requirements to properly notify and how many days the PM has to correct. 

I realized the debt trap I had fallen into had nearly drowned me.My wife and I put all of our debts on paper and decided  that we were no longer using debt for our personal finances.We got married last August and since then we paid off all our debts:$17,000 Wife’s Student loan$25,000 Credit card debt on one card$3509 credit card #2$500 credit card #3$3000 HELOC$12,000 car loan$8000 another car loan$4000 funeral expenses I did it the old fashioned way, lots of hard work and sacrifice.

The existing tenants would not pass my criteria of 3x the monthly rent , 600 credit score, no evictions / credit history since they do not have any credit history / credit cards etc.

It provided first a handy table listing what was stolen as raw strings of data from Equifax’s inadequately protected databases:Full name: 146.6MDate of Birth: 146.6MSocial Security number: 145.5MFull address: 99MGender: 27.3MPhone number: 20.3MDriver’s license number (incl. 2.4M partials): 17.6MEmail address: 1.8MCredit card numbers (with expiration dates): 209,000Individual Tax Identification Number (ITIN/Tax ID): 97,500Driver’s license state: 27,000Previous estimates of driver’s license numbers leaked were around 10.9 million, and total affected put at 143 million.

I’m currently in the process of paying off a couple of fatty credit cards and saving up some cash to get into this business.

I think in return you could provide a welcome gift and thank you for letting you get things ready - this could be something simple like a thank you card and a gift card, welcome mat, or hand soap - something people would need when they are first moving in!
