Market comparables are important as we all know, but they can vary based on finishes and quality of work - so rather than just take the market estimate stated by zillow (as an example), I would ask a local realtor to provide a range of comps and then make sure as you renovating you're actually renovating with a house or two in mind.

So far, I am interested in the midtown area, farmers branch, Las Colinas, and maybe grapevine if something there is in my price range. 

If these were priced individually they would probably go in the 250 to 275 range.

Are there any year ranges of properties that you would avoid for difficulty of updating and rehabbing, i.e. years where lead paint were issues, years where certain building materials where outlawed etc? 

Or like 20 units If each unit would potentially cashflow $250 a month.In the spring of 2022 once the rehab is done and we are able to add some curb appeal to the property I would like to get a HELOC on it as we basically dumped all our liquid savings into it at this Point.Im hoping that it will appraise somewhere in the 290K-300K range with us buying under appraisal value, put 60K documented into it and added a beedroom and bath.

LTV's range from 75-85% depending on your experience and credit score, and are offered in 30 year fixed terms.

If a licensed agent screws a client, the state can step in with actions ranging from fines, to license suspension and ultimately, license revocation.Do your own research by reading the actual TX law.  

Goal & Property Type: Rents in this area range from $800-1200 per bedroom per month and I am looking to have my out of pocket housing expenses to be less than $600 / mo in the best area that I can find with as little down as possible.

That can range...my Mom completed a couple herself a few years ago and it cost ~$1,500 including City fees and survey costs.

So far I have a real estate agent and have been working on getting pre-qualified for a loan so I can get a good idea of what price range to look in.
