Like others have mentioned this is harder than ever with interest rates where they are, but you'll also be able to refinance when interest rates drop.  12 months later (Again this is a rose-colored glasses situation) you'll have access to another 50k from your TSP and potentially a HELOC from the property you purchased, now you have a pile of cash you can use to buy other BRRRRs.

If you are limited on cash, you may want to look at a HELOC on your primary residence to access capital to start flipping or buying rentals.

- How do you vet tenants (screening criteria), marketing, tenant portal access set up once approved and moving in, etc.?

Several of my recent buyers have been medical and legal professionals with high taxable income, that are looking to expand their value portfolios by incorporating an accessible short term rental property (often doubled as a legacy anchor) that will often offset or 'pay for itself,' in tax savings. 

Pay attention to places that have access to amenities, top-notch schools, and job hubs.Value-Added Opportunities: Look for homes that might benefit from upgrades or renovations to raise the value and rental revenue.

I only have access to about $30K so not enough for a 20% down payment.

Definitely want to do them individually to be able to access more cashout .

It's an excellent choice for targeting a wide range of renters, and its convenience and accessibility make it a perennial favorite.With your background, investing in any of these areas with a 1031 Exchange could be a smart play.

As you drive north and around the Eugene airport (with exceptional accessibility and cheap flights to most west coast cities) there are several of the largest homebuilders such as Lennar developing communities as I type..I read an article last week that had Eugene in the top 5 cities that millennials were purchasing homes.

I would like to have access to as much of the land as possible though in the future.
