You may want to use listing spark- which will provide MLS (and other marketing sites) exposure for a fee.

Being an agent will teach you a lot of important skills like sales, negotiating, marketing, and more.

And when you grow too fast (especially in a volatile market like the one we're in) mistakes can get made.

Considering other markets … which are your favs for rentals?

Research the specific market in Buda and the historical appreciation rates for similar properties.

Never has the market been so cornered.

Building relationships with experienced wholesalers can also open doors to joint ventures and off-market deals, giving you a head start in the industry.

I current get $1,000/month for the single and based off local market expect to get $1,500/month for the other part of duplex (mortgage is $2,080/month after putting 20% down).

Begin your 'pre qualification' process for the acquisition now (most commercial lenders won't issue a PreQual but rather a LOI) In general, Commercial transactions can take longer due to extended due diligence, appraisal, environmental reports and financing (60+ days) so you'll want to initiate your search during the marketing of the down leg as it can cause a tighter timeline than a residential transaction. 

I bought it at the peak of the market.
