Hi Lisa, I'm a little late to the conversation but wanted to add a few things. I invest in the Baltimore area and have a few suggestions.
There are several avenues to buy properties with better pricing over what you're looking at. Some things to consider;
1) Why Hampden for your first project? This will be a Class A property for Baltimore once completed based on the rehab cost you're projecting, you can have Class B or B- property for far less money generating a much better return on your investment. As a newbie you have to remember you aren't living in this house so choosing financial planning over a product you could see yourself living in is a key mindset for this business as a newbie.
2) The rehab numbers you're quoting sound like retail numbers or a home with higher-end finishes. Keep in mind that you'll want to connect with a good contractor that will not be paying retail pricing and shouldn't be charging you retail pricing for the rehab.
3) Regarding the contractor, contact several and make sure to get a few bids before selecting a contractor to do the work.
4) Try to connect with a good realtor in the area that can give you hard numbers for your analysis, I don't use "Zestimates" for my rental projections, I use prior 12 month rents for trending and current rent listing actuals in the area of my projects. If you can take a Saturday and visit properties on the area you're interested in and see what the interior finishes are like before overspending to compete with current product on the market.
5) Baltimore can be a good area to build a portfolio, make sure you understand the market within the different neighborhoods, How to use them to obtain your financial goals, and establish relationships within the industry, It'll make investing much easier and cheaper whether you're only doing one property or starting your portfolio.
Hope this helps, Let me know if you have any other questions.
