I've been listening to a lot of BP Podcasts and heard ads of this crowdfunding website.

On large complexes you can look up their website and see if they have a leasing map that identifies address/unit.

For the first one there is a ton of data available on markets through the BP website that you may want to jump into and analyze.For the second one, $300 would be considered great to one person and a waste of time to others.

You can deduct the cost of labor and parts to maintain or repair your business assets, as long as the expense doesn’t prolong the useful life of the asset or increase the value of the asset.Tangible Property Repair Expenses That Are Deductible:Replacement of LightingRoof repairsResurfaced external or interior floorsResurfaced parking lotsInterior or exterior paintingReplacement of doors and windowsRekey locks

But for straightforward setups, you can actually form an LLC directly on the PA Department of State website yourself, and it’s very cost-effective.For larger portfolios or more complex structures, some investors prefer going through a real estate attorney to ensure their LLC is set up to maximize tax benefits and liability protection.

In Denver where I invest it's actually a PLUS to not have the other unit considered separate because permits are only allowed for STR if you're renting out your primary residence and I know many folks who put a locking door on part of their home and have a separate external entrance to that part of the house, and rent it out as an AirBNB without it being considered an additional unit by the city.

As you venture to try and find what cities/areas to buy in might I suggest this resourcehttps://www.areavibes.com/This is a great website to get an over view/starting point for what the neighborhoods are like. 

I have matched both tenants to their Facebook page (not new pages) and their photos on their work websites.

Upright has weekly updates on their website but ya never know 

I have looked at the DFAS website, and haven't gotten very far because I do not have their SSN.
