@Sat Palshetkar - Normally for a househack, and especially where interest rates are right now, you might have to supplement a small amount of the mortgage, however if you take into account that you would have been paying rent, that is far cheaper and you are building equity / wealth.

You can offer discounts for weeklong and boost occupancy, or keep rates high and have mid-weeks empty.A couple of other quick observations - thanks to fracking, we have abundant natural gas in Penna. and may homes have supplemental propane.

I'd probably do something scrappy like take a large personal loan or hard money loan to supplement your $25k, then buy a distressed property and flip it so that then you have a lot more cash to work with.

Sounds like a good time to open a lead paint abatement company to supplement our rental income....lol

Right now, I'm just looking to supplement my income and save money to enhance my RE porfolio.

@Saj Johnson@Tony ManningI have volunteered at my local Area Housing Authority to help resolve conflicts between tenants and the local Area Housing Authority.Remember the majority of section 8 people do not work.they have the time to research all state rental laws and laws that protect them against discrimination.When I mean time eight hours a day seven days a week they can dedicate themselves to this mission.Know the laws that protect them very thoroughly http://www.disabilityrightsca.org/ and http://drlcenter.org/ and https://www.ada.gov/cguide.htmThe section 8 people you want are the ones that work to supplement their government income.

Maybe you can use the money your earning as teacher to help supplement a marketing plan that will enhance what you are already doing so you can build a bigger network closer to where you live.
