Keep in mind that they can increase that period if they get complains from the community, so make sure you're in good relationship with your neighbors.

Hi there, if you're open to holding onto the property, converting it into an Airbnb or short-term rental could significantly increase your cash flow, especially with the current demand for rental properties.

If you have extra cash at the end of the month, then do double up payments on the mortgages so the principle is reduced and this will increase your heloc room.

Quote from @Cameron Moore: Exactly. 15 years ago, I noticed an increase in owners using insurance to pay for a replacement roof, usually to sweeten the pot during a sale.

Not only for the census ending in 2020 but also the projected population from 2020 to 2025.I agree that population increase is important and should be factored in when analyzing a property. 

But once I got the bills, I increased the rent with the tenant's approval and signed an addendum to the lease stating the rent increase would be X and the owner would take over utilities.

The land has slightly increased in value (by like maybe 3-4% over 3 or so years) but the value of the structure I'm pretty sure has gone nowhere. 

We signed P&S agreements on 6 different properties totaling 20 units approximately 8 months ago and received a call today that the price we thought we were buying at has to-be increased on average 13% due to the increased cost of construction.

Even a small increase could make a difference in cash flow.

This would increase the benefit to where the fee would not be so outrageous that it would hinder the investment.
