Currently all 3 leases have expired and they are living there month to month with very little security deposit. 

I doubt I would have had a successful first year otherwise.On average after about 100 phone calls a day to a combination of warm leads, SOI, FSBOs, expired listings, etc should get you about 2 appointments.2 buyer appointments should equate to 1 offer.You should take most of the listing appointments you get.

@Daniel Kurt - Great to e-meet you and welcome to biggerpockets!  

@E.

It always depends on what kind of investing you want to get involved in and assets you have to work with that are liquid or can be made liquid like a 401k transferred into a self-directed IRA for example.

Utilities - $300 seems fineInsurance - $100 - $150 moProperty tax - I'd say 1.25 % would be more accurateMaintenance - I'd allow $500/mo to start a cap fund for when e larger repair is neededInternet - $100 mo is what most pay for a good bandwidth.

Can anyone recommend the best e-sign lease document for Massachusetts?

Date report signed 7-28-21, date of inspection 1-21-21, Expiration date of license or certification 10-31-22 (probably the appraisers license)The executor included appraisal on every correspondence for every property, except the childhood home.Is there any legal recourse I have if this appraiser is doing something shady? 

STR will still offer rental income and you will hopefully have a good CPA who will structure your schedule E correctly for standard deductions and showing a positive net rental. 

They serve some other very real and useful functions as well, and a lot more goes into these than any other typical marketing flier, but marketing is the core function of a preapproval letter.For cash buyers, a bank statement showing the full sales price, in United States dollars, liquid, is of course the best marketing material there is, for that buyer.Onto the question about getting preapproval for a refinance.
