My first piece of advice would be to focus on understanding the market you’re interested in.

I would recommend you focus on a couple neighborhoods that you would like to live in; and familiarize yourself with that market.  

Ultimately you need to understand the underlying economics, psychographics and demographics of the market you are purchasing in to know if and how you can re-tenant the property.I'm a bigger fan of dollar generals or family dollars that are in multi tenant shopping centers. 

You'll have better luck analyzing a few properties a month from investors, wholesalers and realtors that can find you off market deals.

By far your best bet are cheaper markets.

I also have $102k in a money market account that currently earns about 4.5%.

If I gave my number and got it accepted I'd still be nervous, but I'd definitely pull the trigger on the deal.I feel I'm being reasonably cautious without having any recent comps and because the one house in the neighborhood currently on the market is about $15k below his estimated ARV despite being slightly larger.

we can do it not rented but rate will be significantly higher. easier and more cost effective to rent it. unless the bridge money needs to be paid back asap or you need the funds back to buy more, then a cost analysis needs to be done. personally id get it rented at market rent or a touch below if time is a factor. 

In this market, with interest rates and prices at where they are, they're usually not viable (i.e. don't cash flow).

What data do I need to study my market?
